<para>The "cmake" executable is the CMake command-line interface.  It may be used to configure projects in scripts.  Project configuration settings may be specified on the command line with the -D option.  The -i option will cause cmake to interactively prompt for such settings.</para>
<para>CMake is a cross-platform build system generator.  Projects specify their build process with platform-independent CMake listfiles included in each directory of a source tree with the name CMakeLists.txt. Users build a project by using CMake to generate a build system for a native tool on their platform.</para>

    <para id="opt_-C &lt;initial-cache&gt;"><sect2><title>-C &lt;initial-cache&gt;</title></sect2> Pre-load a script to populate the cache.</para>

    <para>When cmake is first run in an empty build tree, it creates a CMakeCache.txt file and populates it with customizable settings for the project.  This option may be used to specify a file from which to load cache entries before the first pass through the project's cmake listfiles.  The loaded entries take priority over the project's default values.  The given file should be a CMake script containing SET commands that use the CACHE option, not a cache-format file.</para>
    <para id="opt_-D &lt;var&gt;:&lt;type&gt;=&lt;value&gt;"><sect2><title>-D &lt;var&gt;:&lt;type&gt;=&lt;value&gt;</title></sect2> Create a cmake cache entry.</para>

    <para>When cmake is first run in an empty build tree, it creates a CMakeCache.txt file and populates it with customizable settings for the project.  This option may be used to specify a setting that takes priority over the project's default value.  The option may be repeated for as many cache entries as desired.</para>
    <para id="opt_-U &lt;globbing_expr&gt;"><sect2><title>-U &lt;globbing_expr&gt;</title></sect2> Remove matching entries from CMake cache.</para>

    <para>This option may be used to remove one or more variables from the CMakeCache.txt file, globbing expressions using * and ? are supported. The option may be repeated for as many cache entries as desired.
</para><para>Use with care, you can make your CMakeCache.txt non-working.</para>
    <para id="opt_-G &lt;generator-name&gt;"><sect2><title>-G &lt;generator-name&gt;</title></sect2> Specify a makefile generator.</para>

    <para>CMake may support multiple native build systems on certain platforms.  A makefile generator is responsible for generating a particular build system.  Possible generator names are specified in the Generators section.</para>
    <para id="opt_-Wno-dev"><sect2><title>-Wno-dev</title></sect2> Suppress developer warnings.</para>

    <para>Suppress warnings that are meant for the author of the CMakeLists.txt files.</para>
    <para id="opt_-Wdev"><sect2><title>-Wdev</title></sect2> Enable developer warnings.</para>

    <para>Enable warnings that are meant for the author of the CMakeLists.txt files.</para>
    <para id="opt_-E"><sect2><title>-E</title></sect2> CMake command mode.</para>

    <para>For true platform independence, CMake provides a list of commands that can be used on all systems. Run with -E help for the usage information. Commands availble are: chdir, copy, copy_if_different copy_directory, compare_files, echo, echo_append, environment, make_directory, md5sum, remove_directory, remove, tar, time, touch, touch_nocreate, write_regv, delete_regv, comspec, create_symlink.</para>
    <para id="opt_-i"><sect2><title>-i</title></sect2> Run in wizard mode.</para>

    <para>Wizard mode runs cmake interactively without a GUI.  The user is prompted to answer questions about the project configuration.  The answers are used to set cmake cache values.</para>
    <para id="opt_-L[A][H]"><sect2><title>-L[A][H]</title></sect2> List non-advanced cached variables.</para>

    <para>List cache variables will run CMake and list all the variables from the CMake cache that are not marked as INTERNAL or ADVANCED. This will effectively display current CMake settings, which can be then changed with -D option. Changing some of the variable may result in more variables being created. If A is specified, then it will display also advanced variables. If H is specified, it will also display help for each variable.</para>
    <para id="opt_-N"><sect2><title>-N</title></sect2> View mode only.</para>

    <para>Only load the cache. Do not actually run configure and generate steps.</para>
    <para id="opt_-P &lt;file&gt;"><sect2><title>-P &lt;file&gt;</title></sect2> Process script mode.</para>

    <para>Process the given cmake file as a script written in the CMake language.  No configure or generate step is performed and the cache is not modified. If variables are defined using -D, this must be done before the -P argument.</para>

    <para id="command_add_custom_command"><sect2><title>add_custom_command</title></sect2> Add a custom build rule to the generated build system.</para>

    <para>There are two main signatures for add_custom_command The first signature is for adding a custom command to produce an output.
</para><literallayout>  add_custom_command(OUTPUT output1 [output2 ...]
                     COMMAND command1 [ARGS] [args1...]
                     [COMMAND command2 [ARGS] [args2...] ...]
                     [MAIN_DEPENDENCY depend]
                     [DEPENDS [depends...]]
                     [IMPLICIT_DEPENDS &lt;lang1&gt; depend1 ...]
                     [WORKING_DIRECTORY dir]
                     [COMMENT comment] [VERBATIM] [APPEND])
</literallayout>
    <para>This defines a new command that can be executed during the build process. The outputs named should be listed as source files in the target for which they are to be generated. If an output name is a relative path it will be interpreted relative to the build tree directory corresponding to the current source directory. Note that MAIN_DEPENDENCY is completely optional and is used as a suggestion to visual studio about where to hang the custom command. In makefile terms this creates a new target in the following form:
</para><literallayout>  OUTPUT: MAIN_DEPENDENCY DEPENDS
          COMMAND
</literallayout>
    <para>If more than one command is specified they will be executed in order. The optional ARGS argument is for backward compatibility and will be ignored.
</para><para>The second signature adds a custom command to a target such as a library or executable. This is useful for performing an operation before or after building the target. The command becomes part of the target and will only execute when the target itself is built.  If the target is already built, the command will not execute.
</para><literallayout>  add_custom_command(TARGET target
                     PRE_BUILD | PRE_LINK | POST_BUILD
                     COMMAND command1 [ARGS] [args1...]
                     [COMMAND command2 [ARGS] [args2...] ...]
                     [WORKING_DIRECTORY dir]
                     [COMMENT comment] [VERBATIM])
</literallayout>
    <para>This defines a new command that will be associated with building the specified target. When the command will happen is determined by which of the following is specified:
</para><literallayout>  PRE_BUILD - run before all other dependencies
  PRE_LINK - run after other dependencies
  POST_BUILD - run after the target has been built
</literallayout>
    <para>Note that the PRE_BUILD option is only supported on Visual Studio 7 or later. For all other generators PRE_BUILD will be treated as PRE_LINK.
</para><para>If WORKING_DIRECTORY is specified the command will be executed in the directory given. If COMMENT is set, the value will be displayed as a message before the commands are executed at build time. If APPEND is specified the COMMAND and DEPENDS option values are appended to the custom command for the first output specified. There must have already been a previous call to this command with the same output. The COMMENT, WORKING_DIRECTORY, and MAIN_DEPENDENCY options are currently ignored when APPEND is given, but may be used in the future.
</para><para>If VERBATIM is given then all the arguments to the commands will be passed exactly as specified no matter the build tool used. Note that one level of escapes is still used by the CMake language processor before ADD_CUSTOM_TARGET even sees the arguments. Use of VERBATIM is recommended as it enables correct behavior. When VERBATIM is not given the behavior is platform specific. In the future VERBATIM may be enabled by default. The only reason it is an option is to preserve compatibility with older CMake code.
</para><para>If the output of the custom command is not actually created as a file on disk it should be marked as SYMBOLIC with SET_SOURCE_FILES_PROPERTIES.
</para><para>The IMPLICIT_DEPENDS option requests scanning of implicit dependencies of an input file.  The language given specifies the programming language whose corresponding dependency scanner should be used.  Currently only C and CXX language scanners are supported. Dependencies discovered from the scanning are added to those of the custom command at build time.  Note that the IMPLICIT_DEPENDS option is currently supported only for Makefile generators and will be ignored by other generators.
</para><para>If COMMAND specifies an executable target (created by ADD_EXECUTABLE) it will automatically be replaced by the location of the executable created at build time.  Additionally a target-level dependency will be added so that the executable target will be built before any target using this custom command.  However this does NOT add a file-level dependency that would cause the custom command to re-run whenever the executable is recompiled.
</para><para>If DEPENDS specifies any target (created by an ADD_* command) a target-level dependency is created to make sure the target is built before any target using this custom command.  Additionally, if the target is an executable or library a file-level dependency is created to cause the custom command to re-run whenever the target is recompiled.
</para>
    <para id="command_add_custom_target"><sect2><title>add_custom_target</title></sect2> Add a target with no output so it will always be built.</para>

    <literallayout>  add_custom_target(Name [ALL] [command1 [args1...]]
                    [COMMAND command2 [args2...] ...]
                    [DEPENDS depend depend depend ... ]
                    [WORKING_DIRECTORY dir]
                    [COMMENT comment] [VERBATIM]
                    [SOURCES src1 [src2...]])
</literallayout>
    <para>Adds a target with the given name that executes the given commands. The target has no output file and is ALWAYS CONSIDERED OUT OF DATE even if the commands try to create a file with the name of the target. Use ADD_CUSTOM_COMMAND to generate a file with dependencies. By default nothing depends on the custom target. Use ADD_DEPENDENCIES to add dependencies to or from other targets. If the ALL option is specified it indicates that this target should be added to the default build target so that it will be run every time (the command cannot be called ALL). The command and arguments are optional and if not specified an empty target will be created. If WORKING_DIRECTORY is set, then the command will be run in that directory. If COMMENT is set, the value will be displayed as a message before the commands are executed at build time. Dependencies listed with the DEPENDS argument may reference files and outputs of custom commands created with ADD_CUSTOM_COMMAND.
</para><para>If VERBATIM is given then all the arguments to the commands will be passed exactly as specified no matter the build tool used. Note that one level of escapes is still used by the CMake language processor before add_custom_target even sees the arguments. Use of VERBATIM is recommended as it enables correct behavior. When VERBATIM is not given the behavior is platform specific. In the future VERBATIM may be enabled by default. The only reason it is an option is to preserve compatibility with older CMake code.
</para><para>The SOURCES option specifies additional source files to be included in the custom target.  Specified source files will be added to IDE project files for convenience in editing even if they have not build rules.</para>
    <para id="command_add_definitions"><sect2><title>add_definitions</title></sect2> Adds -D define flags to the compilation of source files.</para>

    <literallayout>  add_definitions(-DFOO -DBAR ...)
</literallayout>
    <para>Adds flags to the compiler command line for sources in the current directory and below.  This command can be used to add any flags, but it was originally intended to add preprocessor definitions.  Flags beginning in -D or /D that look like preprocessor definitions are automatically added to the COMPILE_DEFINITIONS property for the current directory.  Definitions with non-trival values may be left in the set of flags instead of being converted for reasons of backwards compatibility.  See documentation of the directory, target, and source file COMPILE_DEFINITIONS properties for details on adding preprocessor definitions to specific scopes and configurations.</para>
    <para id="command_add_dependencies"><sect2><title>add_dependencies</title></sect2> Add a dependency between top-level targets.</para>

    <literallayout>  add_dependencies(target-name depend-target1
                   depend-target2 ...)
</literallayout>
    <para>Make a top-level target depend on other top-level targets.  A top-level target is one created by ADD_EXECUTABLE, ADD_LIBRARY, or ADD_CUSTOM_TARGET.  Adding dependencies with this command can be used to make sure one target is built before another target.  See the DEPENDS option of ADD_CUSTOM_TARGET and ADD_CUSTOM_COMMAND for adding file-level dependencies in custom rules.  See the OBJECT_DEPENDS option in SET_SOURCE_FILES_PROPERTIES to add file-level dependencies to object files.</para>
    <para id="command_add_executable"><sect2><title>add_executable</title></sect2> Add an executable to the project using the specified source files.</para>

    <literallayout>  add_executable(&lt;name&gt; [WIN32] [MACOSX_BUNDLE] [EXCLUDE_FROM_ALL]
                 source1 source2 ... sourceN)
</literallayout>
    <para>Adds an executable target called &lt;name&gt; to be built from the source files listed in the command invocation.  The &lt;name&gt; corresponds to the logical target name and must be globally unique within a project.  The actual file name of the executable built is constructed based on conventions of the native platform (such as &lt;name&gt;.exe or just &lt;name&gt;).  
</para><para>By default the executable file will be created in the build tree directory corresponding to the source tree directory in which the command was invoked.  See documentation of the RUNTIME_OUTPUT_DIRECTORY target property to change this location.  See documentation of the OUTPUT_NAME target property to change the &lt;name&gt; part of the final file name.  
</para><para>If WIN32 is given the property WIN32_EXECUTABLE will be set on the target created.  See documentation of that target property for details.
</para><para>If MACOSX_BUNDLE is given the corresponding property will be set on the created target.  See documentation of the MACOSX_BUNDLE target property for details.
</para><para>If EXCLUDE_FROM_ALL is given the corresponding property will be set on the created target.  See documentation of the EXCLUDE_FROM_ALL target property for details.
</para><para>The add_executable command can also create IMPORTED executable targets using this signature:
</para><literallayout>  add_executable(&lt;name&gt; IMPORTED)
</literallayout>
    <para>An IMPORTED executable target references an executable file located outside the project.  No rules are generated to build it.  The target name has scope in the directory in which it is created and below.  It may be referenced like any target built within the project.  IMPORTED executables are useful for convenient reference from commands like add_custom_command.  Details about the imported executable are specified by setting properties whose names begin in "IMPORTED_".  The most important such property is IMPORTED_LOCATION (and its per-configuration version IMPORTED_LOCATION_&lt;CONFIG&gt;) which specifies the location of the main executable file on disk.  See documentation of the IMPORTED_* properties for more information.</para>
    <para id="command_add_library"><sect2><title>add_library</title></sect2> Add a library to the project using the specified source files.</para>

    <literallayout>  add_library(&lt;name&gt; [STATIC | SHARED | MODULE] [EXCLUDE_FROM_ALL]
              source1 source2 ... sourceN)
</literallayout>
    <para>Adds a library target called &lt;name&gt; to be built from the source files listed in the command invocation.  The &lt;name&gt; corresponds to the logical target name and must be globally unique within a project.  The actual file name of the library built is constructed based on conventions of the native platform (such as lib&lt;name&gt;.a or &lt;name&gt;.lib).
</para><para>STATIC, SHARED, or MODULE may be given to specify the type of library to be created.  STATIC libraries are archives of object files for use when linking other targets.  SHARED libraries are linked dynamically and loaded at runtime.  MODULE libraries are plugins that are not linked into other targets but may be loaded dynamically at runtime using dlopen-like functionality.  If no type is given explicitly the type is STATIC or SHARED based on whether the current value of the variable BUILD_SHARED_LIBS is true.
</para><para>By default the library file will be created in the build tree directory corresponding to the source tree directory in which the command was invoked.  See documentation of the ARCHIVE_OUTPUT_DIRECTORY, LIBRARY_OUTPUT_DIRECTORY, and RUNTIME_OUTPUT_DIRECTORY target properties to change this location.  See documentation of the OUTPUT_NAME target property to change the &lt;name&gt; part of the final file name.  
</para><para>If EXCLUDE_FROM_ALL is given the corresponding property will be set on the created target.  See documentation of the EXCLUDE_FROM_ALL target property for details.
</para><para>The add_library command can also create IMPORTED library targets using this signature:
</para><literallayout>  add_library(&lt;name&gt; &lt;SHARED|STATIC|MODULE|UNKNOWN&gt; IMPORTED)
</literallayout>
    <para>An IMPORTED library target references a library file located outside the project.  No rules are generated to build it.  The target name has scope in the directory in which it is created and below.  It may be referenced like any target built within the project.  IMPORTED libraries are useful for convenient reference from commands like target_link_libraries.  Details about the imported library are specified by setting properties whose names begin in "IMPORTED_".  The most important such property is IMPORTED_LOCATION (and its per-configuration version IMPORTED_LOCATION_&lt;CONFIG&gt;) which specifies the location of the main library file on disk.  See documentation of the IMPORTED_* properties for more information.</para>
    <para id="command_add_subdirectory"><sect2><title>add_subdirectory</title></sect2> Add a subdirectory to the build.</para>

    <literallayout>  add_subdirectory(source_dir [binary_dir] 
                   [EXCLUDE_FROM_ALL])
</literallayout>
    <para>Add a subdirectory to the build. The source_dir specifies the directory in which the source CmakeLists.txt and code files are located. If it is a relative path it will be evaluated with respect to the current directory (the typical usage), but it may also be an absolute path. The binary_dir specifies the directory in which to place the output files. If it is a relative path it will be evaluated with respect to the current output directory, but it may also be an absolute path. If binary_dir is not specified, the value of source_dir, before expanding any relative path, will be used (the typical usage). The CMakeLists.txt file in the specified source directory will be processed immediately by CMake before processing in the current input file continues beyond this command.
</para><para>If the EXCLUDE_FROM_ALL argument is provided then targets in the subdirectory will not be included in the ALL target of the parent directory by default, and will be excluded from IDE project files.  Users must explicitly build targets in the subdirectory.  This is meant for use when the subdirectory contains a separate part of the project that is useful but not necessary, such as a set of examples.  Typically the subdirectory should contain its own project() command invocation so that a full build system will be generated in the subdirectory (such as a VS IDE solution file).  Note that inter-target dependencies supercede this exclusion.  If a target built by the parent project depends on a target in the subdirectory, the dependee target will be included in the parent project build system to satisfy the dependency.</para>
    <para id="command_add_test"><sect2><title>add_test</title></sect2> Add a test to the project with the specified arguments.</para>

    <literallayout>  add_test(testname Exename arg1 arg2 ...)
</literallayout>
    <para>If the ENABLE_TESTING command has been run, this command adds a test target to the current directory. If ENABLE_TESTING has not been run, this command does nothing.  The tests are run by the testing subsystem by executing Exename with the specified arguments.  Exename can be either an executable built by this project or an arbitrary executable on the system (like tclsh).  The test will be run with the current working directory set to the CMakeList.txt files corresponding directory in the binary tree.</para>
    <para id="command_aux_source_directory"><sect2><title>aux_source_directory</title></sect2> Find all source files in a directory.</para>

    <literallayout>  aux_source_directory(&lt;dir&gt; &lt;variable&gt;)
</literallayout>
    <para>Collects the names of all the source files in the specified directory and stores the list in the &lt;variable&gt; provided.  This command is intended to be used by projects that use explicit template instantiation.  Template instantiation files can be stored in a "Templates" subdirectory and collected automatically using this command to avoid manually listing all instantiations.
</para><para>It is tempting to use this command to avoid writing the list of source files for a library or executable target.  While this seems to work, there is no way for CMake to generate a build system that knows when a new source file has been added.  Normally the generated build system knows when it needs to rerun CMake because the CMakeLists.txt file is modified to add a new source.  When the source is just added to the directory without modifying this file, one would have to manually rerun CMake to generate a build system incorporating the new file.</para>
    <para id="command_break"><sect2><title>break</title></sect2> Break from an enclosing foreach or while loop.</para>

    <literallayout>  break()
</literallayout>
    <para>Breaks from an enclosing foreach loop or while loop</para>
    <para id="command_build_command"><sect2><title>build_command</title></sect2> Get the command line that will build this project.</para>

    <literallayout>  build_command(&lt;variable&gt; &lt;makecommand&gt;)
</literallayout>
    <para>Sets the given &lt;variable&gt; to a string containing the command that will build this project from the root of the build tree using the build tool given by &lt;makecommand&gt;.  &lt;makecommand&gt; should be msdev, nmake, make or one of the end user build tools.  This is useful for configuring testing systems.</para>
    <para id="command_cmake_minimum_required"><sect2><title>cmake_minimum_required</title></sect2> Set the minimum required version of cmake for a project.</para>

    <literallayout>  cmake_minimum_required(VERSION major[.minor[.patch]]
                         [FATAL_ERROR])
</literallayout>
    <para>If the current version of CMake is lower than that required it will stop processing the project and report an error.  When a version higher than 2.4 is specified the command implicitly invokes
</para><literallayout>  cmake_policy(VERSION major[.minor[.patch]])

    <para>As CMake evolves it is sometimes necessary to change existing behavior in order to fix bugs or improve implementations of existing features.  The CMake Policy mechanism is designed to help keep existing projects building as new versions of CMake introduce changes in behavior.  Each new policy (behavioral change) is given an identifier of the form "CMP&lt;NNNN&gt;" where "&lt;NNNN&gt;" is an integer index.  Documentation associated with each policy describes the OLD and NEW behavior and the reason the policy was introduced.  Projects may set each policy to select the desired behavior.  When CMake needs to know which behavior to use it checks for a setting specified by the project.  If no setting is available the OLD behavior is assumed and a warning is produced requesting that the policy be set.
</para><para>The cmake_policy command is used to set policies to OLD or NEW behavior.  While setting policies individually is supported, we encourage projects to set policies based on CMake versions.
</para><literallayout>  cmake_policy(VERSION major.minor[.patch])
</literallayout>
    <para>Specify that the current CMake list file is written for the given version of CMake.  All policies introduced in the specified version or earlier will be set to use NEW behavior.  All policies introduced after the specified version will be reset to use OLD behavior with a warning.  This effectively requests behavior preferred as of a given CMake version and tells newer CMake versions to warn about their new policies.  The policy version specified must be at least 2.4 or the command will report an error.  In order to get compatibility features supporting versions earlier than 2.4 see documentation of policy CMP0001.
</para><literallayout>  cmake_policy(SET CMP&lt;NNNN&gt; NEW)
  cmake_policy(SET CMP&lt;NNNN&gt; OLD)
</literallayout>
    <para>Tell CMake to use the OLD or NEW behavior for a given policy.  Projects depending on the old behavior of a given policy may silence a policy warning by setting the policy state to OLD.  Alternatively one may fix the project to work with the new behavior and set the policy state to NEW.
</para><literallayout>  cmake_policy(GET CMP&lt;NNNN&gt; &lt;variable&gt;)
</literallayout>
    <para>Check whether a given policy is set to OLD or NEW behavior.  The output variable value will be "OLD" or "NEW" if the policy is set, and empty otherwise.
</para><para>CMake keeps policy settings on a stack, so changes made by the cmake_policy command affect only the top of the stack.  A new entry on the policy stack is managed automatically for each subdirectory to protect its parents and siblings.  CMake also manages a new entry for scripts loaded by include() and find_package() commands except when invoked with the NO_POLICY_SCOPE option (see also policy CMP0011).  The cmake_policy command provides an interface to manage custom entries on the policy stack:
</para><literallayout>  cmake_policy(PUSH)
  cmake_policy(POP)
</literallayout>
    <para>Each PUSH must have a matching POP to erase any changes.  This is useful to make temporary changes to policy settings.
</para><para>Functions and macros record policy settings when they are created and use the pre-record policies when they are invoked.  If the function or macro implementation sets policies, the changes automatically propagate up through callers until they reach the closest nested policy stack entry.</para>

    <para>The Input and Output files have to have full paths.  This command replaces any variables in the input file referenced as ${VAR} or @VAR@ with their values as determined by CMake.  If a variable is not defined, it will be replaced with nothing.  If COPYONLY is specified, then no variable expansion will take place.  If ESCAPE_QUOTES is specified then any substituted quotes will be C-style escaped.  The file will be configured with the current values of CMake variables. If @ONLY is specified, only variables of the form @VAR@ will be replaces and ${VAR} will be ignored.  This is useful for configuring scripts that use ${VAR}. Any occurrences of #cmakedefine VAR will be replaced with either #define VAR or /* #undef VAR */ depending on the setting of VAR in CMake</para>

    <para>A test driver is a program that links together many small tests into a single executable.  This is useful when building static executables with large libraries to shrink the total required size.  The list of source files needed to build the test driver will be in sourceListName.  DriverName is the name of the test driver program.  The rest of the arguments consist of a list of test source files, can be semicolon separated.  Each test source file should have a function in it that is the same name as the file with no extension (foo.cxx should have int foo(int, char*[]);) DriverName will be able to call each of the tests by name on the command line. If EXTRA_INCLUDE is specified, then the next argument is included into the generated file. If FUNCTION is specified, then the next argument is taken as a function name that is passed a pointer to ac and av.  This can be used to add extra command line processing to each test. The cmake variable CMAKE_TESTDRIVER_BEFORE_TESTMAIN can be set to have code that will be placed directly before calling the test main function.   CMAKE_TESTDRIVER_AFTER_TESTMAIN can be set to have code that will be placed directly after the call to the test main function.</para>

    <para>The CMake variable CMAKE_FIND_ROOT_PATH specifies one or more directories to be prepended to all other search directories. This effectively "re-roots" the entire search under given locations. By default it is empty.

By default at first the directories listed in CMAKE_FIND_ROOT_PATH and then the non-rooted directories will be searched. The default behavior can be adjusted by setting CMAKE_FIND_ROOT_PATH_MODE_INCLUDE.  This behavior can be manually overridden on a per-call basis. By using CMAKE_FIND_ROOT_PATH_BOTH the search order will be as described above. If NO_CMAKE_FIND_ROOT_PATH is used then CMAKE_FIND_ROOT_PATH will not be used.

For example ENV PATH would be a way to list the system path variable. The argument after DOC will be used for the documentation string in the cache.  PATH_SUFFIXES specifies additional subdirectories to check below each search path.
</para><para>If NO_DEFAULT_PATH is specified, then no additional paths are added to the search. If NO_DEFAULT_PATH is not specified, the search process is as follows:

    <para>The CMake variable CMAKE_FIND_ROOT_PATH specifies one or more directories to be prepended to all other search directories. This effectively "re-roots" the entire search under given locations. By default it is empty. It is especially useful when cross-compiling to point to the root directory of the target environment and CMake will search there too. By default at first the directories listed in CMAKE_FIND_ROOT_PATH and then the non-rooted directories will be searched. The default behavior can be adjusted by setting CMAKE_FIND_ROOT_PATH_MODE_LIBRARY.  This behavior can be manually overridden on a per-call basis. By using CMAKE_FIND_ROOT_PATH_BOTH the search order will be as described above. If NO_CMAKE_FIND_ROOT_PATH is used then CMAKE_FIND_ROOT_PATH will not be used. If ONLY_CMAKE_FIND_ROOT_PATH is used then only the re-rooted directories will be searched.
</para><para>The default search order is designed to be most-specific to least-specific for common use cases.  Projects may override the order by simply calling the command multiple times and using the NO_* options:

    <para>Finds and loads settings from an external project.  &lt;package&gt;_FOUND will be set to indicate whether the package was found.  When the package is found package-specific information is provided through variables documented by the package itself.  The QUIET option disables messages if the package cannot be found.  The REQUIRED option stops processing with an error message if the package cannot be found.  A package-specific list of components may be listed after the REQUIRED option or after the COMPONENTS option if no REQUIRED option is given.  The [version] argument requests a version with which the package found should be compatible (format is major[.minor[.patch[.tweak]]]).  The EXACT option requests that the version be matched exactly.  If no [version] is given to a recursive invocation inside a find-module, the [version] and EXACT arguments are forwarded automatically from the outer call.  Version support is currently provided only on a package-by-package basis (details below).
</para><para>User code should generally look for packages using the above simple signature.  The remainder of this command documentation specifies the full command signature and details of the search process.  Project maintainers wishing to provide a package to be found by this command are encouraged to read on.
</para><para>The command has two modes by which it searches for packages: "Module" mode and "Config" mode.  Module mode is available when the command is invoked with the above reduced signature.  CMake searches for a file called "Find&lt;package&gt;.cmake" in the CMAKE_MODULE_PATH followed by the CMake installation.  If the file is found, it is read and processed by CMake.  It is responsible for finding the package, checking the version, and producing any needed messages.  Many find-modules provide limited or no support for versioning; check the module documentation.  If no module is found the command proceeds to Config mode.
</para><para>The complete Config mode command signature is:

</literallayout>
    <para>The NO_MODULE option may be used to skip Module mode explicitly.  It is also implied by use of options not specified in the reduced signature.  
</para><para>Config mode attempts to locate a configuration file provided by the package to be found.  A cache entry called &lt;package&gt;_DIR is created to hold the directory containing the file.  By default the command searches for a package with the name &lt;package&gt;.  If the NAMES option is given the names following it are used instead of &lt;package&gt;.  The command searches for a file called "&lt;name&gt;Config.cmake" or "&lt;lower-case-name&gt;-config.cmake" for each name specified.  A replacement set of possible configuration file names may be given using the CONFIGS option.  The search procedure is specified below.  Once found, the configuration file is read and processed by CMake.  Since the file is provided by the package it already knows the location of package contents.  The full path to the configuration file is stored in the cmake variable &lt;package&gt;_CONFIG.
</para><para>If the package configuration file cannot be found CMake will generate an error describing the problem unless the QUIET argument is specified.  If REQUIRED is specified and the package is not found a fatal error is generated and the configure step stops executing.  If &lt;package&gt;_DIR has been set to a directory not containing a configuration file CMake will ignore it and search from scratch.
</para><para>When the [version] argument is given Config mode will only find a version of the package that claims compatibility with the requested version (format is major[.minor[.patch[.tweak]]]).  If the EXACT option is given only a version of the package claiming an exact match of the requested version may be found.  CMake does not establish any convention for the meaning of version numbers.  Package version numbers are checked by "version" files provided by the packages themselves.  For a candidate package confguration file "&lt;config-file&gt;.cmake" the corresponding version file is located next to it and named either "&lt;config-file&gt;-version.cmake" or "&lt;config-file&gt;Version.cmake".  If no such version file is available then the configuration file is assumed to not be compatible with any requested version.  When a version file is found it is loaded to check the requested version number.  The version file is loaded in a nested scope in which the following variables have been defined:
</para><literallayout>  PACKAGE_FIND_NAME          = the &lt;package&gt; name
  PACKAGE_FIND_VERSION       = full requested version string
  PACKAGE_FIND_VERSION_MAJOR = major version if requested, else 0
  PACKAGE_FIND_VERSION_MINOR = minor version if requested, else 0
  PACKAGE_FIND_VERSION_PATCH = patch version if requested, else 0
  PACKAGE_FIND_VERSION_TWEAK = tweak version if requested, else 0
  PACKAGE_FIND_VERSION_COUNT = number of version components, 0 to 4
</literallayout>
    <para>The version file checks whether it satisfies the requested version and sets these variables:
</para><literallayout>  PACKAGE_VERSION            = full provided version string
  PACKAGE_VERSION_EXACT      = true if version is exact match
  PACKAGE_VERSION_COMPATIBLE = true if version is compatible
  PACKAGE_VERSION_UNSUITABLE = true if unsuitable as any version
</literallayout>
    <para>These variables are checked by the find_package command to determine whether the configuration file provides an acceptable version.  They are not available after the find_package call returns.  If the version is acceptable the following variables are set:
</para><literallayout>  &lt;package&gt;_VERSION       = full provided version string
  &lt;package&gt;_VERSION_MAJOR = major version if provided, else 0
  &lt;package&gt;_VERSION_MINOR = minor version if provided, else 0
  &lt;package&gt;_VERSION_PATCH = patch version if provided, else 0
  &lt;package&gt;_VERSION_TWEAK = tweak version if provided, else 0
  &lt;package&gt;_VERSION_COUNT = number of version components, 0 to 4
</literallayout>
    <para>and the corresponding package configuration file is loaded.  When multiple package configuration files are available whose version files claim compatibility with the version requested it is unspecified which one is chosen.  No attempt is made to choose a highest or closest version number.
</para><para>Config mode provides an elaborate interface and search procedure.  Much of the interface is provided for completeness and for use internally by find-modules loaded by Module mode.  Most user code should simply call

    <para>This command is used to find a program. A cache entry named by &lt;VAR&gt; is created to store the result of this command.  If the program is found the result is stored in the variable and the search will not be repeated unless the variable is cleared.  If nothing is found, the result will be &lt;VAR&gt;-NOTFOUND, and the search will be attempted again the next time find_program is invoked with the same variable.  The name of the program that is searched for is specified by the names listed after the NAMES argument.   Additional search locations can be specified after the PATHS argument.  If ENV var is found in the HINTS or PATHS section the environment variable var will be read and converted from a system environment variable to a cmake style list of paths.  For example ENV PATH would be a way to list the system path variable. The argument after DOC will be used for the documentation string in the cache.  PATH_SUFFIXES specifies additional subdirectories to check below each search path.
</para><para>If NO_DEFAULT_PATH is specified, then no additional paths are added to the search. If NO_DEFAULT_PATH is not specified, the search process is as follows:
</para><para>1. Search paths specified in cmake-specific cache variables.  These are intended to be used on the command line with a -DVAR=value.  This can be skipped if NO_CMAKE_PATH is passed.
</para><literallayout>   &lt;prefix&gt;/[s]bin for each &lt;prefix&gt; in CMAKE_PREFIX_PATH
   CMAKE_PROGRAM_PATH
   CMAKE_APPBUNDLE_PATH
</literallayout>
    <para>2. Search paths specified in cmake-specific environment variables.  These are intended to be set in the user's shell configuration.  This can be skipped if NO_CMAKE_ENVIRONMENT_PATH is passed.
</para><literallayout>   &lt;prefix&gt;/[s]bin for each &lt;prefix&gt; in CMAKE_PREFIX_PATH
   CMAKE_PROGRAM_PATH
   CMAKE_APPBUNDLE_PATH
</literallayout>
    <para>3. Search the paths specified by the HINTS option.  These should be paths computed by system introspection, such as a hint provided by the location of another item already found.  Hard-coded guesses should be specified with the PATHS option.
</para><para>4. Search the standard system environment variables. This can be skipped if NO_SYSTEM_ENVIRONMENT_PATH is an argument.
</para><literallayout>   PATH
   
</literallayout>
    <para>5. Search cmake variables defined in the Platform files for the current system.  This can be skipped if NO_CMAKE_SYSTEM_PATH is passed.

    <para>6. Search the paths specified by the PATHS option or in the short-hand version of the command.  These are typically hard-coded guesses.
</para><para>On Darwin or systems supporting OS X Frameworks, the cmake variable    CMAKE_FIND_FRAMEWORK can be set to empty or one of the following:
</para><literallayout>   "FIRST"  - Try to find frameworks before standard
              libraries or headers. This is the default on Darwin.
   "LAST"   - Try to find frameworks after standard
              libraries or headers.
   "ONLY"   - Only try to find frameworks.
   "NEVER". - Never try to find frameworks.
</literallayout>
    <para>On Darwin or systems supporting OS X Application Bundles, the cmake variable CMAKE_FIND_APPBUNDLE can be set to empty or one of the following:
</para><literallayout>   "FIRST"  - Try to find application bundles before standard
              programs. This is the default on Darwin.
   "LAST"   - Try to find application bundles after standard

   "ONLY"   - Only try to find application bundles.
   "NEVER". - Never try to find application bundles.
</literallayout>
    <para>The CMake variable CMAKE_FIND_ROOT_PATH specifies one or more directories to be prepended to all other search directories. This effectively "re-roots" the entire search under given locations. By default it is empty. It is especially useful when cross-compiling to point to the root directory of the target environment and CMake will search there too. By default at first the directories listed in CMAKE_FIND_ROOT_PATH and then the non-rooted directories will be searched. The default behavior can be adjusted by setting CMAKE_FIND_ROOT_PATH_MODE_PROGRAM.  This behavior can be manually overridden on a per-call basis. By using CMAKE_FIND_ROOT_PATH_BOTH the search order will be as described above. If NO_CMAKE_FIND_ROOT_PATH is used then CMAKE_FIND_ROOT_PATH will not be used. If ONLY_CMAKE_FIND_ROOT_PATH is used then only the re-rooted directories will be searched.
</para><para>The default search order is designed to be most-specific to least-specific for common use cases.  Projects may override the order by simply calling the command multiple times and using the NO_* options:
</para><literallayout>   find_program(&lt;VAR&gt; NAMES name PATHS paths... NO_DEFAULT_PATH)
   find_program(&lt;VAR&gt; NAMES name)

    <para>Define a function named &lt;name&gt; that takes arguments named arg1 arg2 arg3 (...).  Commands listed after function, but before the matching endfunction, are not invoked until the function is invoked.  When it is invoked, the commands recorded in the function are first modified by replacing formal parameters (${arg1}) with the arguments passed, and then invoked as normal commands. In addition to referencing the formal parameters you can reference the variable ARGC which will be set to the number of arguments passed into the function as well as ARGV0 ARGV1 ARGV2 ... which will have the actual values of the arguments passed in. This facilitates creating functions with optional arguments. Additionally ARGV holds the list of all arguments given to the function and ARGN holds the list of argument pass the last expected argument.

</para><para>There are multiple signatures for this command.  Some of them define installation properties for files and targets.  Properties common to multiple signatures are covered here but they are valid only for signatures that specify them.
</para><para>DESTINATION arguments specify the directory on disk to which a file will be installed.  If a full path (with a leading slash or drive letter) is given it is used directly.  If a relative path is given it is interpreted relative to the value of CMAKE_INSTALL_PREFIX.
</para><para>PERMISSIONS arguments specify permissions for installed files.  Valid permissions are OWNER_READ, OWNER_WRITE, OWNER_EXECUTE, GROUP_READ, GROUP_WRITE, GROUP_EXECUTE, WORLD_READ, WORLD_WRITE, WORLD_EXECUTE, SETUID, and SETGID.  Permissions that do not make sense on certain platforms are ignored on those platforms.
</para><para>The CONFIGURATIONS argument specifies a list of build configurations for which the install rule applies (Debug, Release, etc.).
</para><para>The COMPONENT argument specifies an installation component name with which the install rule is associated, such as "runtime" or "development".  During component-specific installation only install rules associated with the given component name will be executed.  During a full installation all components are installed.
</para><para>The RENAME argument specifies a name for an installed file that may be different from the original file.  Renaming is allowed only when a single file is installed by the command.
</para><para>The OPTIONAL argument specifies that it is not an error if the file to be installed does not exist.  
</para><para>The TARGETS signature:

           [OPTIONAL] [NAMELINK_ONLY|NAMELINK_SKIP]
          ] [...])
</literallayout>
    <para>The TARGETS form specifies rules for installing targets from a project.  There are five kinds of target files that may be installed: ARCHIVE, LIBRARY, RUNTIME, FRAMEWORK, and BUNDLE.  Executables are treated as RUNTIME targets, except that those marked with the MACOSX_BUNDLE property are treated as BUNDLE targets on OS X. Static libraries are always treated as ARCHIVE targets. Module libraries are always treated as LIBRARY targets. For non-DLL platforms shared libraries are treated as LIBRARY targets, except that those marked with the FRAMEWORK property are treated as FRAMEWORK targets on OS X.  For DLL platforms the DLL part of a shared library is treated as a RUNTIME target and the corresponding import library is treated as an ARCHIVE target. All Windows-based systems including Cygwin are DLL platforms. The ARCHIVE, LIBRARY, RUNTIME, and FRAMEWORK arguments change the type of target to which the subsequent properties apply.  If none is given the installation properties apply to all target types.  If only one is given then only targets of that type will be installed (which can be used to install just a DLL or just an import library).
</para><para>The PRIVATE_HEADER, PUBLIC_HEADER, and RESOURCE arguments cause subsequent properties to be applied to installing a FRAMEWORK shared library target's associated files on non-Apple platforms.  Rules defined by these arguments are ignored on Apple platforms because the associated files are installed into the appropriate locations inside the framework folder.  See documentation of the PRIVATE_HEADER, PUBLIC_HEADER, and RESOURCE target properties for details.
</para><para>Either NAMELINK_ONLY or NAMELINK_SKIP may be specified as a LIBRARY option.  On some platforms a versioned shared library has a symbolic link such as
</para><literallayout>  lib&lt;name&gt;.so -&gt; lib&lt;name&gt;.so.1
</literallayout>
    <para>where "lib&lt;name&gt;.so.1" is the soname of the library and "lib&lt;name&gt;.so" is a "namelink" allowing linkers to find the library when given "-l&lt;name&gt;".  The NAMELINK_ONLY option causes installation of only the namelink when a library target is installed.  The NAMELINK_SKIP option causes installation of library files other than the namelink when a library target is installed.  When neither option is given both portions are installed.  On platforms where versioned shared libraries do not have namelinks or when a library is not versioned the NAMELINK_SKIP option installs the library and the NAMELINK_ONLY option installs nothing.  See the VERSION and SOVERSION target properties for details on creating versioned shared libraries.
</para><para>One or more groups of properties may be specified in a single call to the TARGETS form of this command.  A target may be installed more than once to different locations.  Consider hypothetical targets "myExe", "mySharedLib", and "myStaticLib".  The code
</para><literallayout>    install(TARGETS myExe mySharedLib myStaticLib
            RUNTIME DESTINATION bin
            LIBRARY DESTINATION lib
            ARCHIVE DESTINATION lib/static)
    install(TARGETS mySharedLib DESTINATION /some/full/path)
</literallayout>
    <para>will install myExe to &lt;prefix&gt;/bin and myStaticLib to &lt;prefix&gt;/lib/static.  On non-DLL platforms mySharedLib will be installed to &lt;prefix&gt;/lib and /some/full/path.  On DLL platforms the mySharedLib DLL will be installed to &lt;prefix&gt;/bin and /some/full/path and its import library will be installed to &lt;prefix&gt;/lib/static and /some/full/path. On non-DLL platforms mySharedLib will be installed to &lt;prefix&gt;/lib and /some/full/path.
</para><para>The EXPORT option associates the installed target files with an export called &lt;export-name&gt;.  It must appear before any RUNTIME, LIBRARY, or ARCHIVE options.  See documentation of the install(EXPORT ...) signature below for details.
</para><para>Installing a target with EXCLUDE_FROM_ALL set to true has undefined behavior.
</para><para>The FILES signature:
</para><literallayout>  install(FILES files... DESTINATION &lt;dir&gt;

          [RENAME &lt;name&gt;] [OPTIONAL])
</literallayout>
    <para>The FILES form specifies rules for installing files for a project.  File names given as relative paths are interpreted with respect to the current source directory.  Files installed by this form are by default given permissions OWNER_WRITE, OWNER_READ, GROUP_READ, and WORLD_READ if no PERMISSIONS argument is given.
</para><para>The PROGRAMS signature:
</para><literallayout>  install(PROGRAMS files... DESTINATION &lt;dir&gt;
          [PERMISSIONS permissions...]
          [CONFIGURATIONS [Debug|Release|...]]
          [COMPONENT &lt;component&gt;]
          [RENAME &lt;name&gt;] [OPTIONAL])
</literallayout>
    <para>The PROGRAMS form is identical to the FILES form except that the default permissions for the installed file also include OWNER_EXECUTE, GROUP_EXECUTE, and WORLD_EXECUTE.  This form is intended to install programs that are not targets, such as shell scripts.  Use the TARGETS form to install targets built within the project.
</para><para>The DIRECTORY signature:
</para><literallayout>  install(DIRECTORY dirs... DESTINATION &lt;dir&gt;
          [FILE_PERMISSIONS permissions...]
          [DIRECTORY_PERMISSIONS permissions...]
          [USE_SOURCE_PERMISSIONS]
          [CONFIGURATIONS [Debug|Release|...]]
          [COMPONENT &lt;component&gt;] [FILES_MATCHING]
          [[PATTERN &lt;pattern&gt; | REGEX &lt;regex&gt;]
           [EXCLUDE] [PERMISSIONS permissions...]] [...])
</literallayout>
    <para>The DIRECTORY form installs contents of one or more directories to a given destination.  The directory structure is copied verbatim to the destination.  The last component of each directory name is appended to the destination directory but a trailing slash may be used to avoid this because it leaves the last component empty.  Directory names given as relative paths are interpreted with respect to the current source directory.  If no input directory names are given the destination directory will be created but nothing will be installed into it.  The FILE_PERMISSIONS and DIRECTORY_PERMISSIONS options specify permissions given to files and directories in the destination.  If USE_SOURCE_PERMISSIONS is specified and FILE_PERMISSIONS is not, file permissions will be copied from the source directory structure.  If no permissions are specified files will be given the default permissions specified in the FILES form of the command, and the directories will be given the default permissions specified in the PROGRAMS form of the command.
</para><para>Installation of directories may be controlled with fine granularity using the PATTERN or REGEX options.  These "match" options specify a globbing pattern or regular expression to match directories or files encountered within input directories.  They may be used to apply certain options (see below) to a subset of the files and directories encountered.  The full path to each input file or directory (with forward slashes) is matched against the expression.  A PATTERN will match only complete file names: the portion of the full path matching the pattern must occur at the end of the file name and be preceded by a slash.  A REGEX will match any portion of the full path but it may use '/' and '$' to simulate the PATTERN behavior.  By default all files and directories are installed whether or not they are matched.  The FILES_MATCHING option may be given before the first match option to disable installation of files (but not directories) not matched by any expression.  For example, the code
</para><literallayout>  install(DIRECTORY src/ DESTINATION include/myproj
          FILES_MATCHING PATTERN "*.h")
</literallayout>
    <para>will extract and install header files from a source tree.
</para><para>Some options may follow a PATTERN or REGEX expression and are applied only to files or directories matching them.  The EXCLUDE option will skip the matched file or directory.  The PERMISSIONS option overrides the permissions setting for the matched file or directory.  For example the code
</para><literallayout>  install(DIRECTORY icons scripts/ DESTINATION share/myproj
          PATTERN "CVS" EXCLUDE
          PATTERN "scripts/*"
          PERMISSIONS OWNER_EXECUTE OWNER_WRITE OWNER_READ
                      GROUP_EXECUTE GROUP_READ)
</literallayout>
    <para>will install the icons directory to share/myproj/icons and the scripts directory to share/myproj.  The icons will get default file permissions, the scripts will be given specific permissions, and any CVS directories will be excluded.
</para><para>The SCRIPT and CODE signature:
</para><literallayout>  install([[SCRIPT &lt;file&gt;] [CODE &lt;code&gt;]] [...])
</literallayout>
    <para>The SCRIPT form will invoke the given CMake script files during installation.  If the script file name is a relative path it will be interpreted with respect to the current source directory.  The CODE form will invoke the given CMake code during installation.  Code is specified as a single argument inside a double-quoted string. For example, the code
</para><literallayout>  install(CODE "MESSAGE(\"Sample install message.\")")
</literallayout>
    <para>will print a message during installation.
</para><para>The EXPORT signature:
</para><literallayout>  install(EXPORT &lt;export-name&gt; DESTINATION &lt;dir&gt;
          [NAMESPACE &lt;namespace&gt;] [FILE &lt;name&gt;.cmake]
          [PERMISSIONS permissions...]
          [CONFIGURATIONS [Debug|Release|...]]
          [COMPONENT &lt;component&gt;])
</literallayout>
    <para>The EXPORT form generates and installs a CMake file containing code to import targets from the installation tree into another project.  Target installations are associated with the export &lt;export-name&gt; using the EXPORT option of the install(TARGETS ...) signature documented above.  The NAMESPACE option will prepend &lt;namespace&gt; to the target names as they are written to the import file.  By default the generated file will be called &lt;export-name&gt;.cmake but the FILE option may be used to specify a different name.  The value given to the FILE option must be a file name with the ".cmake" extension.  If a CONFIGURATIONS option is given then the file will only be installed when one of the named configurations is installed.  Additionally, the generated import file will reference only the matching target configurations.  If a COMPONENT option is specified that does not match that given to the targets associated with &lt;export-name&gt; the behavior is undefined.  If a library target is included in the export but a target to which it links is not included the behavior is unspecified.
</para><para>The EXPORT form is useful to help outside projects use targets built and installed by the current project.  For example, the code
</para><literallayout>  install(TARGETS myexe EXPORT myproj DESTINATION bin)
  install(EXPORT myproj NAMESPACE mp_ DESTINATION lib/myproj)
</literallayout>
    <para>will install the executable myexe to &lt;prefix&gt;/bin and code to import it in the file "&lt;prefix&gt;/lib/myproj/myproj.cmake".  An outside project may load this file with the include command and reference the myexe executable from the installation tree using the imported target name mp_myexe as if the target were built in its own tree.
</para><para>NOTE: This command supercedes the INSTALL_TARGETS command and the target properties PRE_INSTALL_SCRIPT and POST_INSTALL_SCRIPT.  It also replaces the FILES forms of the INSTALL_FILES and INSTALL_PROGRAMS commands.  The processing order of these install rules relative to those generated by INSTALL_TARGETS, INSTALL_FILES, and INSTALL_PROGRAMS commands is not defined.

</literallayout>
    <para>LENGTH will return a given list's length.
</para><para>GET will return list of elements specified by indices from the list.
</para><para>APPEND will append elements to the list.
</para><para>FIND will return the index of the element specified in the list or -1 if it wasn't found.
</para><para>INSERT will insert elements to the list to the specified location.
</para><para>REMOVE_AT and REMOVE_ITEM will remove items from the list. The difference is that REMOVE_ITEM will remove the given items, while REMOVE_AT will remove the items at the given indices.
</para><para>REMOVE_DUPLICATES will remove duplicated items in the list.
</para><para>REVERSE reverses the contents of the list in-place.
</para><para>SORT sorts the list in-place alphabetically.
</para><para>NOTES: A list in cmake is a ; separated group of strings. To create a list the set command can be used. For example, set(var a b c d e)  creates a list with a;b;c;d;e, and set(var "a b c d e") creates a string or a list with one item in it.
</para><para>When specifying index values, if &lt;element index&gt; is 0 or greater, it is indexed from the beginning of the list, with 0 representing the first list element. If &lt;element index&gt; is -1 or lesser, it is indexed from the end of the list, with -1 representing the last list element. Be careful when counting with negative indices: they do not start from 0. -0 is equivalent to 0, the first list element.

    <para>Define a macro named &lt;name&gt; that takes arguments named arg1 arg2 arg3 (...).  Commands listed after macro, but before the matching endmacro, are not invoked until the macro is invoked.  When it is invoked, the commands recorded in the macro are first modified by replacing formal parameters (${arg1}) with the arguments passed, and then invoked as normal commands. In addition to referencing the formal parameters you can reference the values ${ARGC} which will be set to the number of arguments passed into the function as well as ${ARGV0} ${ARGV1} ${ARGV2} ... which will have the actual values of the arguments passed in. This facilitates creating macros with optional arguments. Additionally ${ARGV} holds the list of all arguments given to the macro and ${ARGN} holds the list of argument pass the last expected argument. Note that the parameters to a macro and values such as ARGN are not variables in the usual CMake sense. They are string replacements much like the c preprocessor would do with a macro. If you want true CMake variables you should look at the function command.

</literallayout>
    <para>Set properties on a file. The syntax for the command is to list all the files you want to change, and then provide the values you want to set next.  You can make up your own properties as well.  The following are used by CMake.  The ABSTRACT flag (boolean) is used by some class wrapping commands. If WRAP_EXCLUDE (boolean) is true then many wrapping commands will ignore this file. If GENERATED (boolean) is true then it is not an error if this source file does not exist when it is added to a target.  Obviously, it must be created (presumably by a custom command) before the target is built.  If the HEADER_FILE_ONLY (boolean) property is true then the file is not compiled.  This is useful if you want to add extra non build files to an IDE. OBJECT_DEPENDS (string) adds dependencies to the object file.  COMPILE_FLAGS (string) is passed to the compiler as additional command line arguments when the source file is compiled.  LANGUAGE (string) CXX|C will change the default compiler used to compile the source file. The languages used need to be enabled in the PROJECT command. If SYMBOLIC (boolean) is set to true the build system will be informed that the source file is not actually created on disk but instead used as a symbolic name for a build rule.</para>

</literallayout>
    <para>Set properties on a target. The syntax for the command is to list all the files you want to change, and then provide the values you want to set next.  You can use any prop value pair you want and extract it later with the GET_TARGET_PROPERTY command.
</para><para>Properties that affect the name of a target's output file are as follows.  The PREFIX and SUFFIX properties override the default target name prefix (such as "lib") and suffix (such as ".so"). IMPORT_PREFIX and IMPORT_SUFFIX are the equivalent properties for the import library corresponding to a DLL (for SHARED library targets).  OUTPUT_NAME sets the real name of a target when it is built and can be used to help create two targets of the same name even though CMake requires unique logical target names.  There is also a &lt;CONFIG&gt;_OUTPUT_NAME that can set the output name on a per-configuration basis.  &lt;CONFIG&gt;_POSTFIX sets a postfix for the real name of the target when it is built under the configuration named by &lt;CONFIG&gt; (in upper-case, such as "DEBUG_POSTFIX").  The value of this property is initialized when the target is created to the value of the variable CMAKE_&lt;CONFIG&gt;_POSTFIX (except for executable targets because earlier CMake versions which did not use this variable for executables).
</para><para>The LINK_FLAGS property can be used to add extra flags to the link step of a target. LINK_FLAGS_&lt;CONFIG&gt; will add to the configuration &lt;CONFIG&gt;, for example, DEBUG, RELEASE, MINSIZEREL, RELWITHDEBINFO. DEFINE_SYMBOL sets the name of the preprocessor symbol defined when compiling sources in a shared library. If not set here then it is set to target_EXPORTS by default (with some substitutions if the target is not a valid C identifier). This is useful for headers to know whether they are being included from inside their library our outside to properly setup dllexport/dllimport decorations. The COMPILE_FLAGS property sets additional compiler flags used to build sources within the target.  It may also be used to pass additional preprocessor definitions.
</para><para>The LINKER_LANGUAGE property is used to change the tool used to link an executable or shared library. The default is set the language to match the files in the library. CXX and C are common values for this property.
</para><para>For shared libraries VERSION and SOVERSION can be used to specify the build version and api version respectively. When building or installing appropriate symlinks are created if the platform supports symlinks and the linker supports so-names. If only one of both is specified the missing is assumed to have the same version number. For executables VERSION can be used to specify the build version. When building or installing appropriate symlinks are created if the platform supports symlinks. For shared libraries and executables on Windows the VERSION attribute is parsed to extract a "major.minor" version number. These numbers are used as the image version of the binary. 
</para><para>There are a few properties used to specify RPATH rules. INSTALL_RPATH is a semicolon-separated list specifying the rpath to use in installed targets (for platforms that support it). INSTALL_RPATH_USE_LINK_PATH is a boolean that if set to true will append directories in the linker search path and outside the project to the INSTALL_RPATH. SKIP_BUILD_RPATH is a boolean specifying whether to skip automatic generation of an rpath allowing the target to run from the build tree. BUILD_WITH_INSTALL_RPATH is a boolean specifying whether to link the target in the build tree with the INSTALL_RPATH.  This takes precedence over SKIP_BUILD_RPATH and avoids the need for relinking before installation.  INSTALL_NAME_DIR is a string specifying the directory portion of the "install_name" field of shared libraries on Mac OSX to use in the installed targets. When the target is created the values of the variables CMAKE_INSTALL_RPATH, CMAKE_INSTALL_RPATH_USE_LINK_PATH, CMAKE_SKIP_BUILD_RPATH, CMAKE_BUILD_WITH_INSTALL_RPATH, and CMAKE_INSTALL_NAME_DIR are used to initialize these properties.
</para><para>PROJECT_LABEL can be used to change the name of the target in an IDE like visual studio.  VS_KEYWORD can be set to change the visual studio keyword, for example QT integration works better if this is set to Qt4VSv1.0.
</para><para>VS_SCC_PROJECTNAME, VS_SCC_LOCALPATH, VS_SCC_PROVIDER can be set to add support for source control bindings in a  Visual Studio project file.
</para><para>When a library is built CMake by default generates code to remove any existing library using all possible names.  This is needed to support libraries that switch between STATIC and SHARED by a user option.  However when using OUTPUT_NAME to build a static and shared library of the same name using different logical target names the two targets will remove each other's files.  This can be prevented by setting the CLEAN_DIRECT_OUTPUT property to 1.
</para><para>The PRE_INSTALL_SCRIPT and POST_INSTALL_SCRIPT properties are the old way to specify CMake scripts to run before and after installing a target.  They are used only when the old INSTALL_TARGETS command is used to install the target.  Use the INSTALL command instead.
</para><para>The EXCLUDE_FROM_DEFAULT_BUILD property is used by the visual studio generators.  If it is set to 1 the target will not be part of the default build when you select "Build Solution".</para>

</para><para>
</para><para>Cross compiling issues
</para><para>When cross compiling, the executable compiled in the first step usually cannot be run on the build host. try_run() checks the CMAKE_CROSSCOMPILING variable to detect whether CMake is in crosscompiling mode. If that's the case, it will still try to compile the executable, but it will not try to run the executable. Instead it will create cache variables which must be filled by the user or by presetting them in some CMake script file to the values the executable would have produced if it would have been run on its actual target platform. These variables are RUN_RESULT_VAR (explanation see above) and if RUN_OUTPUT_VARIABLE (or OUTPUT_VARIABLE) was used, an additional cache variable RUN_RESULT_VAR__COMPILE_RESULT_VAR__TRYRUN_OUTPUT.This is intended to hold stdout and stderr from the executable.
</para><para>In order to make cross compiling your project easier, use try_run only if really required. If you use try_run, use RUN_OUTPUT_VARIABLE (or OUTPUT_VARIABLE) only if really required. Using them will require that when crosscompiling, the cache variables will have to be set manually to the output of the executable. You can also "guard" the calls to try_run with if(CMAKE_CROSSCOMPILING) and provide an easy-to-preset alternative for this case.

    <para id="prop_dir_COMPILE_DEFINITIONS"><sect2><title>COMPILE_DEFINITIONS</title></sect2> Preprocessor definitions for compiling a directory's sources.</para>

    <para>The COMPILE_DEFINITIONS property may be set to a list of preprocessor definitions using the syntax VAR or VAR=value.  Function-style definitions are not supported.  CMake will automatically escape the value correctly for the native build system (note that CMake language syntax may require escapes to specify some values).  This property may be set on a per-configuration basis using the name COMPILE_DEFINITIONS_&lt;CONFIG&gt; where &lt;CONFIG&gt; is an upper-case name (ex. "COMPILE_DEFINITIONS_DEBUG").  This property will be initialized in each directory by its value in the directory's parent.
</para><para>CMake will automatically drop some definitions that are not supported by the native build tool.  The VS6 IDE does not support definitions with values (but NMake does).
</para><para>Dislaimer: Most native build tools have poor support for escaping certain values.  CMake has work-arounds for many cases but some values may just not be possible to pass correctly.  If a value does not seem to be escaped correctly, do not attempt to work-around the problem by adding escape sequences to the value.  Your work-around may break in a future version of CMake that has improved escape support.  Instead consider defining the macro in a (configured) header file.  Then report the limitation.</para>
    <para id="prop_dir_COMPILE_DEFINITIONS_&lt;CONFIG&gt;"><sect2><title>COMPILE_DEFINITIONS_&lt;CONFIG&gt;</title></sect2> Per-configuration preprocessor definitions in a directory.</para>

    <para>This is the configuration-specific version of COMPILE_DEFINITIONS.  This property will be initialized in each directory by its value in the directory's parent.
</para>
    <para id="prop_dir_DEFINITIONS"><sect2><title>DEFINITIONS</title></sect2> For CMake 2.4 compatibility only.  Use COMPILE_DEFINITIONS instead.</para>

    <para id="prop_dir_EXCLUDE_FROM_ALL"><sect2><title>EXCLUDE_FROM_ALL</title></sect2> Exclude the directory from the all target of its parent.</para>

    <para>A property on a directory that indicates if its targets are excluded from the default build target. If it is not, then with a Makefile for example typing make will cause the targets to be built. The same concept applies to the default build of other generators.</para>
    <para id="prop_dir_IMPLICIT_DEPENDS_INCLUDE_TRANSFORM"><sect2><title>IMPLICIT_DEPENDS_INCLUDE_TRANSFORM</title></sect2> Specify #include line transforms for dependencies in a directory.</para>

    <para>This property specifies rules to transform macro-like #include lines during implicit dependency scanning of C and C++ source files.  The list of rules must be semicolon-separated with each entry of the form "A_MACRO(%)=value-with-%" (the % must be literal).  During dependency scanning occurrences of A_MACRO(...) on #include lines will be replaced by the value given with the macro argument substituted for '%'.  For example, the entry
</para><literallayout>  MYDIR(%)=&lt;mydir/%&gt;

    <para id="prop_tgt_&lt;CONFIG&gt;_POSTFIX"><sect2><title>&lt;CONFIG&gt;_POSTFIX</title></sect2> Postfix to append to the target file name for configuration &lt;CONFIG&gt;.</para>

    <para>When building with configuration &lt;CONFIG&gt; the value of this property is appended to the target file name built on disk.  For non-executable targets, this property is initialized by the value of the variable CMAKE_&lt;CONFIG&gt;_POSTFIX if it is set when a target is created.  This property is ignored on the Mac for Frameworks and App Bundles.</para>
    <para id="prop_tgt_ARCHIVE_OUTPUT_DIRECTORY"><sect2><title>ARCHIVE_OUTPUT_DIRECTORY</title></sect2> Output directory in which to build ARCHIVE target files.</para>

    <para>This property specifies the directory into which archive target files should be built. There are three kinds of target files that may be built: archive, library, and runtime.  Executables are always treated as runtime targets. Static libraries are always treated as archive targets. Module libraries are always treated as library targets. For non-DLL platforms shared libraries are treated as library targets. For DLL platforms the DLL part of a shared library is treated as a runtime target and the corresponding import library is treated as an archive target. All Windows-based systems including Cygwin are DLL platforms. This property is initialized by the value of the variable CMAKE_ARCHIVE_OUTPUT_DIRECTORY if it is set when a target is created.</para>
    <para id="prop_tgt_BUILD_WITH_INSTALL_RPATH"><sect2><title>BUILD_WITH_INSTALL_RPATH</title></sect2> Should build tree targets have install tree rpaths.</para>

    <para>BUILD_WITH_INSTALL_RPATH is a boolean specifying whether to link the target in the build tree with the INSTALL_RPATH.  This takes precedence over SKIP_BUILD_RPATH and avoids the need for relinking before installation.</para>
    <para id="prop_tgt_CLEAN_DIRECT_OUTPUT"><sect2><title>CLEAN_DIRECT_OUTPUT</title></sect2> Do not delete other variants of this target.</para>

    <para>When a library is built CMake by default generates code to remove any existing library using all possible names.  This is needed to support libraries that switch between STATIC and SHARED by a user option.  However when using OUTPUT_NAME to build a static and shared library of the same name using different logical target names the two targets will remove each other's files.  This can be prevented by setting the CLEAN_DIRECT_OUTPUT property to 1.</para>
    <para id="prop_tgt_COMPILE_DEFINITIONS"><sect2><title>COMPILE_DEFINITIONS</title></sect2> Preprocessor definitions for compiling a target's sources.</para>

    <para>The COMPILE_DEFINITIONS property may be set to a list of preprocessor definitions using the syntax VAR or VAR=value.  Function-style definitions are not supported.  CMake will automatically escape the value correctly for the native build system (note that CMake language syntax may require escapes to specify some values).  This property may be set on a per-configuration basis using the name COMPILE_DEFINITIONS_&lt;CONFIG&gt; where &lt;CONFIG&gt; is an upper-case name (ex. "COMPILE_DEFINITIONS_DEBUG").
</para><para>CMake will automatically drop some definitions that are not supported by the native build tool.  The VS6 IDE does not support definitions with values (but NMake does).
</para><para>Dislaimer: Most native build tools have poor support for escaping certain values.  CMake has work-arounds for many cases but some values may just not be possible to pass correctly.  If a value does not seem to be escaped correctly, do not attempt to work-around the problem by adding escape sequences to the value.  Your work-around may break in a future version of CMake that has improved escape support.  Instead consider defining the macro in a (configured) header file.  Then report the limitation.</para>
    <para id="prop_tgt_COMPILE_DEFINITIONS_&lt;CONFIG&gt;"><sect2><title>COMPILE_DEFINITIONS_&lt;CONFIG&gt;</title></sect2> Per-configuration preprocessor definitions on a target.</para>

    <para>This is the configuration-specific version of COMPILE_DEFINITIONS.</para>
    <para id="prop_tgt_COMPILE_FLAGS"><sect2><title>COMPILE_FLAGS</title></sect2> Additional flags to use when compiling this target's sources.</para>

    <para>The COMPILE_FLAGS property sets additional compiler flags used to build sources within the target.  Use COMPILE_DEFINITIONS to pass additional preprocessor definitions.</para>
    <para id="prop_tgt_DEBUG_POSTFIX"><sect2><title>DEBUG_POSTFIX</title></sect2> See target property &lt;CONFIG&gt;_POSTFIX.</para>

    <para>This property is a special case of the more-general &lt;CONFIG&gt;_POSTFIX property for the DEBUG configuration.</para>
    <para id="prop_tgt_DEFINE_SYMBOL"><sect2><title>DEFINE_SYMBOL</title></sect2> Define a symbol when compiling this target's sources.</para>

    <para>DEFINE_SYMBOL sets the name of the preprocessor symbol defined when compiling sources in a shared library. If not set here then it is set to target_EXPORTS by default (with some substitutions if the target is not a valid C identifier). This is useful for headers to know whether they are being included from inside their library our outside to properly setup dllexport/dllimport decorations. </para>
    <para id="prop_tgt_ENABLE_EXPORTS"><sect2><title>ENABLE_EXPORTS</title></sect2> Specify whether an executable exports symbols for loadable modules.</para>

    <para>Normally an executable does not export any symbols because it is the final program.  It is possible for an executable to export symbols to be used by loadable modules.  When this property is set to true CMake will allow other targets to "link" to the executable with the TARGET_LINK_LIBRARIES command.  On all platforms a target-level dependency on the executable is created for targets that link to it.  For non-DLL platforms the link rule is simply ignored since the dynamic loader will automatically bind symbols when the module is loaded.  For DLL platforms an import library will be created for the exported symbols and then used for linking.  All Windows-based systems including Cygwin are DLL platforms.</para>
    <para id="prop_tgt_EXCLUDE_FROM_ALL"><sect2><title>EXCLUDE_FROM_ALL</title></sect2> Exclude the target from the all target.</para>

    <para>A property on a target that indicates if the target is excluded from the default build target. If it is not, then with a Makefile for example typing make will cause this target to be built. The same concept applies to the default build of other generators. Installing a target with EXCLUDE_FROM_ALL set to true has undefined behavior.</para>
    <para id="prop_tgt_EchoString"><sect2><title>EchoString</title></sect2> A message to be displayed when the target is built.</para>

    <para>A message to display on some generators (such as makefiles) when the target is built.</para>
    <para id="prop_tgt_FRAMEWORK"><sect2><title>FRAMEWORK</title></sect2> This target is a framework on the Mac.</para>

    <para>If a shared library target has this property set to true it will be built as a framework when built on the mac. It will have the directory structure required for a framework and will be suitable to be used with the -framework option</para>
    <para id="prop_tgt_Fortran_MODULE_DIRECTORY"><sect2><title>Fortran_MODULE_DIRECTORY</title></sect2> Specify output directory for Fortran modules provided by the target.</para>

    <para>If the target contains Fortran source files that provide modules and the compiler supports a module output directory this specifies the directory in which the modules will be placed.  When this property is not set the modules will be placed in the build directory corresponding to the target's source directory.  If the variable CMAKE_Fortran_MODULE_DIRECTORY is set when a target is created its value is used to initialize this property.</para>
    <para id="prop_tgt_GENERATOR_FILE_NAME"><sect2><title>GENERATOR_FILE_NAME</title></sect2> Generator's file for this target.</para>

    <para>An internal property used by some generators to record the name of project or dsp file associated with this target.</para>
    <para id="prop_tgt_HAS_CXX"><sect2><title>HAS_CXX</title></sect2> Force a target to use the CXX linker.</para>

    <para>Setting HAS_CXX on a target will force the target to use the C++ linker (and C++ runtime libraries) for linking even if the target has no C++ code in it.</para>
    <para id="prop_tgt_IMPLICIT_DEPENDS_INCLUDE_TRANSFORM"><sect2><title>IMPLICIT_DEPENDS_INCLUDE_TRANSFORM</title></sect2> Specify #include line transforms for dependencies in a target.</para>

    <para>This property specifies rules to transform macro-like #include lines during implicit dependency scanning of C and C++ source files.  The list of rules must be semicolon-separated with each entry of the form "A_MACRO(%)=value-with-%" (the % must be literal).  During dependency scanning occurrences of A_MACRO(...) on #include lines will be replaced by the value given with the macro argument substituted for '%'.  For example, the entry
</para><literallayout>  MYDIR(%)=&lt;mydir/%&gt;
</literallayout>
    <para>will convert lines of the form
</para><literallayout>  #include MYDIR(myheader.h)
</literallayout>
    <para>to
</para><literallayout>  #include &lt;mydir/myheader.h&gt;
</literallayout>
    <para>allowing the dependency to be followed.
</para><para>This property applies to sources in the target on which it is set.</para>
    <para id="prop_tgt_IMPORTED"><sect2><title>IMPORTED</title></sect2> Read-only indication of whether a target is IMPORTED.</para>

    <para>The boolean value of this property is true for targets created with the IMPORTED option to add_executable or add_library.  It is false for targets built within the project.</para>
    <para id="prop_tgt_IMPORTED_CONFIGURATIONS"><sect2><title>IMPORTED_CONFIGURATIONS</title></sect2> Configurations provided for an IMPORTED target.</para>

    <para>Lists configuration names available for an IMPORTED target.  The names correspond to configurations defined in the project from which the target is imported.  If the importing project uses a different set of configurations the names may be mapped using the MAP_IMPORTED_CONFIG_&lt;CONFIG&gt; property.  Ignored for non-imported targets.</para>
    <para id="prop_tgt_IMPORTED_IMPLIB"><sect2><title>IMPORTED_IMPLIB</title></sect2> Full path to the import library for an IMPORTED target.</para>

    <para>Specifies the location of the ".lib" part of a windows DLL.  Ignored for non-imported targets.</para>
    <para id="prop_tgt_IMPORTED_IMPLIB_&lt;CONFIG&gt;"><sect2><title>IMPORTED_IMPLIB_&lt;CONFIG&gt;</title></sect2> Per-configuration version of IMPORTED_IMPLIB property.</para>

    <para>This property is used when loading settings for the &lt;CONFIG&gt; configuration of an imported target.  Configuration names correspond to those provided by the project from which the target is imported.</para>
    <para id="prop_tgt_IMPORTED_LINK_DEPENDENT_LIBRARIES"><sect2><title>IMPORTED_LINK_DEPENDENT_LIBRARIES</title></sect2> Dependent shared libraries of an imported shared library.</para>

    <para>Shared libraries may be linked to other shared libraries as part of their implementation.  On some platforms the linker searches for the dependent libraries of shared libraries they are including in the link.  This property lists the dependent shared libraries of an imported library.  The list should be disjoint from the list of interface libraries in the IMPORTED_LINK_INTERFACE_LIBRARIES property.  On platforms requiring dependent shared libraries to be found at link time CMake uses this list to add appropriate files or paths to the link command line.  Ignored for non-imported targets.</para>
    <para id="prop_tgt_IMPORTED_LINK_DEPENDENT_LIBRARIES_&lt;CONFIG&gt;"><sect2><title>IMPORTED_LINK_DEPENDENT_LIBRARIES_&lt;CONFIG&gt;</title></sect2> Per-configuration version of IMPORTED_LINK_DEPENDENT_LIBRARIES.</para>

    <para>This property is used when loading settings for the &lt;CONFIG&gt; configuration of an imported target.  Configuration names correspond to those provided by the project from which the target is imported.  If set, this property completely overrides the generic property for the named configuration.</para>
    <para id="prop_tgt_IMPORTED_LINK_INTERFACE_LIBRARIES"><sect2><title>IMPORTED_LINK_INTERFACE_LIBRARIES</title></sect2> Transitive link interface of an IMPORTED target.</para>

    <para>Lists libraries whose interface is included when an IMPORTED library target is linked to another target.  The libraries will be included on the link line for the target.  Unlike the LINK_INTERFACE_LIBRARIES property, this property applies to all imported target types, including STATIC libraries.  This property is ignored for non-imported targets.</para>
    <para id="prop_tgt_IMPORTED_LINK_INTERFACE_LIBRARIES_&lt;CONFIG&gt;"><sect2><title>IMPORTED_LINK_INTERFACE_LIBRARIES_&lt;CONFIG&gt;</title></sect2> Per-configuration version of IMPORTED_LINK_INTERFACE_LIBRARIES.</para>

    <para>This property is used when loading settings for the &lt;CONFIG&gt; configuration of an imported target.  Configuration names correspond to those provided by the project from which the target is imported.  If set, this property completely overrides the generic property for the named configuration.</para>
    <para id="prop_tgt_IMPORTED_LOCATION"><sect2><title>IMPORTED_LOCATION</title></sect2> Full path to the main file on disk for an IMPORTED target.</para>

    <para>Specifies the location of an IMPORTED target file on disk.  For executables this is the location of the executable file.  For bundles on OS X this is the location of the executable file inside Contents/MacOS under the application bundle folder.  For static libraries and modules this is the location of the library or module.  For shared libraries on non-DLL platforms this is the location of the shared library.  For frameworks on OS X this is the location of the library file symlink just inside the framework folder.  For DLLs this is the location of the ".dll" part of the library.  For UNKNOWN libraries this is the location of the file to be linked.  Ignored for non-imported targets.</para>
    <para id="prop_tgt_IMPORTED_LOCATION_&lt;CONFIG&gt;"><sect2><title>IMPORTED_LOCATION_&lt;CONFIG&gt;</title></sect2> Per-configuration version of IMPORTED_LOCATION property.</para>

    <para>This property is used when loading settings for the &lt;CONFIG&gt; configuration of an imported target.  Configuration names correspond to those provided by the project from which the target is imported.</para>
    <para id="prop_tgt_IMPORTED_SONAME"><sect2><title>IMPORTED_SONAME</title></sect2> The "soname" of an IMPORTED target of shared library type.</para>

    <para>Specifies the "soname" embedded in an imported shared library.  This is meaningful only on platforms supporting the feature.  Ignored for non-imported targets.</para>
    <para id="prop_tgt_IMPORTED_SONAME_&lt;CONFIG&gt;"><sect2><title>IMPORTED_SONAME_&lt;CONFIG&gt;</title></sect2> Per-configuration version of IMPORTED_SONAME property.</para>

    <para>This property is used when loading settings for the &lt;CONFIG&gt; configuration of an imported target.  Configuration names correspond to those provided by the project from which the target is imported.</para>
    <para id="prop_tgt_IMPORT_PREFIX"><sect2><title>IMPORT_PREFIX</title></sect2> What comes before the import library name.</para>

    <para>Similar to the target property PREFIX, but used for import libraries (typically corresponding to a DLL) instead of regular libraries. A target property that can be set to override the prefix (such as "lib") on an import library name.</para>
    <para id="prop_tgt_IMPORT_SUFFIX"><sect2><title>IMPORT_SUFFIX</title></sect2> What comes after the import library name.</para>

    <para>Similar to the target property SUFFIX, but used for import libraries (typically corresponding to a DLL) instead of regular libraries. A target property that can be set to override the suffix (such as ".lib") on an import library name.</para>
    <para id="prop_tgt_INSTALL_NAME_DIR"><sect2><title>INSTALL_NAME_DIR</title></sect2> Mac OSX directory name for installed targets.</para>

    <para>INSTALL_NAME_DIR is a string specifying the directory portion of the "install_name" field of shared libraries on Mac OSX to use in the installed targets. </para>
    <para id="prop_tgt_INSTALL_RPATH"><sect2><title>INSTALL_RPATH</title></sect2> The rpath to use for installed targets.</para>

    <para>A semicolon-separated list specifying the rpath to use in installed targets (for platforms that support it).</para>
    <para id="prop_tgt_INSTALL_RPATH_USE_LINK_PATH"><sect2><title>INSTALL_RPATH_USE_LINK_PATH</title></sect2> Add paths to linker search and installed rpath.</para>

    <para>INSTALL_RPATH_USE_LINK_PATH is a boolean that if set to true will append directories in the linker search path and outside the project to the INSTALL_RPATH. </para>
    <para id="prop_tgt_LIBRARY_OUTPUT_DIRECTORY"><sect2><title>LIBRARY_OUTPUT_DIRECTORY</title></sect2> Output directory in which to build LIBRARY target files.</para>

    <para>This property specifies the directory into which library target files should be built. There are three kinds of target files that may be built: archive, library, and runtime.  Executables are always treated as runtime targets. Static libraries are always treated as archive targets. Module libraries are always treated as library targets. For non-DLL platforms shared libraries are treated as library targets. For DLL platforms the DLL part of a shared library is treated as a runtime target and the corresponding import library is treated as an archive target. All Windows-based systems including Cygwin are DLL platforms. This property is initialized by the value of the variable CMAKE_LIBRARY_OUTPUT_DIRECTORY if it is set when a target is created.</para>
    <para id="prop_tgt_LINKER_LANGUAGE"><sect2><title>LINKER_LANGUAGE</title></sect2> What tool to use for linking, based on language.</para>

    <para>The LINKER_LANGUAGE property is used to change the tool used to link an executable or shared library. The default is set the language to match the files in the library. CXX and C are common values for this property.</para>
    <para id="prop_tgt_LINK_FLAGS"><sect2><title>LINK_FLAGS</title></sect2> Additional flags to use when linking this target.</para>

    <para>The LINK_FLAGS property can be used to add extra flags to the link step of a target. LINK_FLAGS_&lt;CONFIG&gt; will add to the configuration &lt;CONFIG&gt;, for example, DEBUG, RELEASE, MINSIZEREL, RELWITHDEBINFO. </para>
    <para id="prop_tgt_LINK_FLAGS_&lt;CONFIG&gt;"><sect2><title>LINK_FLAGS_&lt;CONFIG&gt;</title></sect2> Per-configuration linker flags for a target.</para>

    <para>This is the configuration-specific version of LINK_FLAGS.</para>
    <para id="prop_tgt_LINK_INTERFACE_LIBRARIES"><sect2><title>LINK_INTERFACE_LIBRARIES</title></sect2> List public interface libraries for a shared library or executable.</para>

    <para>By default linking to a shared library target transitively links to targets with which the library itself was linked.  For an executable with exports (see the ENABLE_EXPORTS property) no default transitive link dependencies are used.  This property replaces the default transitive link dependencies with an explict list.  When the target is linked into another target the libraries listed (and recursively their link interface libraries) will be provided to the other target also.  If the list is empty then no transitive link dependencies will be incorporated when this target is linked into another target even if the default set is non-empty.  This property is ignored for STATIC libraries.</para>
    <para id="prop_tgt_LINK_INTERFACE_LIBRARIES_&lt;CONFIG&gt;"><sect2><title>LINK_INTERFACE_LIBRARIES_&lt;CONFIG&gt;</title></sect2> Per-configuration list of public interface libraries for a target.</para>

    <para>This is the configuration-specific version of LINK_INTERFACE_LIBRARIES.  If set, this property completely overrides the generic property for the named configuration.</para>
    <para id="prop_tgt_LINK_SEARCH_END_STATIC"><sect2><title>LINK_SEARCH_END_STATIC</title></sect2> End a link line such that static system libraries are used.</para>

    <para>Some linkers support switches such as -Bstatic and -Bdynamic to determine whether to use static or shared libraries for -lXXX options.  CMake uses these options to set the link type for libraries whose full paths are not known or (in some cases) are in implicit link directories for the platform.  By default the linker search type is left at -Bdynamic by the end of the library list.  This property switches the final linker search type to -Bstatic.</para>
    <para id="prop_tgt_LOCATION"><sect2><title>LOCATION</title></sect2> Read-only location of a target on disk.</para>

    <para>For an imported target, this read-only property returns the value of the LOCATION_&lt;CONFIG&gt; property for an unspecified configuration &lt;CONFIG&gt; provided by the target.
</para><para>For a non-imported target, this property is provided for compatibility with CMake 2.4 and below.  It was meant to get the location of an executable target's output file for use in add_custom_command.  The path may contain a build-system-specific portion that is replaced at build time with the configuration getting built (such as "$(ConfigurationName)" in VS). In CMake 2.6 and above add_custom_command automatically recognizes a target name in its COMMAND and DEPENDS options and computes the target location.  Therefore this property is not needed for creating custom commands.</para>
    <para id="prop_tgt_LOCATION_&lt;CONFIG&gt;"><sect2><title>LOCATION_&lt;CONFIG&gt;</title></sect2> Read-only property providing a target location on disk.</para>

    <para>A read-only property that indicates where a target's main file is located on disk for the configuration &lt;CONFIG&gt;.  The property is defined only for library and executable targets.  An imported target may provide a set of configurations different from that of the importing project.  By default CMake looks for an exact-match but otherwise uses an arbitrary available configuration.  Use the MAP_IMPORTED_CONFIG_&lt;CONFIG&gt; property to map imported configurations explicitly.</para>
    <para id="prop_tgt_MACOSX_BUNDLE"><sect2><title>MACOSX_BUNDLE</title></sect2> Build an executable as an application bundle on Mac OS X.</para>

    <para>When this property is set to true the executable when built on Mac OS X will be created as an application bundle.  This makes it a GUI executable that can be launched from the Finder.  See the MACOSX_BUNDLE_INFO_PLIST target property for information about creation of the Info.plist file for the application bundle.</para>
    <para id="prop_tgt_MACOSX_BUNDLE_INFO_PLIST"><sect2><title>MACOSX_BUNDLE_INFO_PLIST</title></sect2> Specify a custom Info.plist template for a Mac OS X App Bundle.</para>

    <para>An executable target with MACOSX_BUNDLE enabled will be built as an application bundle on Mac OS X.  By default its Info.plist file is created by configuring a template called MacOSXBundleInfo.plist.in located in the CMAKE_MODULE_PATH.  This property specifies an alternative template file name which may be a full path.
</para><para>The following target properties may be set to specify content to be configured into the file:
</para><literallayout>  MACOSX_BUNDLE_INFO_STRING
  MACOSX_BUNDLE_ICON_FILE
  MACOSX_BUNDLE_GUI_IDENTIFIER

  MACOSX_BUNDLE_BUNDLE_VERSION
  MACOSX_BUNDLE_COPYRIGHT
</literallayout>
    <para>CMake variables of the same name may be set to affect all targets in a directory that do not have each specific property set.  If a custom Info.plist is specified by this property it may of course hard-code all the settings instead of using the target properties.</para>
    <para id="prop_tgt_MACOSX_FRAMEWORK_INFO_PLIST"><sect2><title>MACOSX_FRAMEWORK_INFO_PLIST</title></sect2> Specify a custom Info.plist template for a Mac OS X Framework.</para>

    <para>An library target with FRAMEWORK enabled will be built as a framework on Mac OS X.  By default its Info.plist file is created by configuring a template called MacOSXFrameworkInfo.plist.in located in the CMAKE_MODULE_PATH.  This property specifies an alternative template file name which may be a full path.

    <para id="prop_tgt_MAP_IMPORTED_CONFIG_&lt;CONFIG&gt;"><sect2><title>MAP_IMPORTED_CONFIG_&lt;CONFIG&gt;</title></sect2> Map from project configuration to IMPORTED target's configuration.</para>

    <para>List configurations of an imported target that may be used for the current project's &lt;CONFIG&gt; configuration.  Targets imported from another project may not provide the same set of configuration names available in the current project.  Setting this property tells CMake what imported configurations are suitable for use when building the &lt;CONFIG&gt; configuration.  The first configuration in the list found to be provided by the imported target is selected.  If no matching configurations are available the imported target is considered to be not found.  This property is ignored for non-imported targets.</para>
    <para id="prop_tgt_OUTPUT_NAME"><sect2><title>OUTPUT_NAME</title></sect2> Sets the real name of a target when it is built.</para>

    <para>Sets the real name of a target when it is built and can be used to help create two targets of the same name even though CMake requires unique logical target names.  There is also a &lt;CONFIG&gt;_OUTPUT_NAME that can set the output name on a per-configuration basis.</para>
    <para id="prop_tgt_POST_INSTALL_SCRIPT"><sect2><title>POST_INSTALL_SCRIPT</title></sect2> Deprecated install support.</para>

    <para>The PRE_INSTALL_SCRIPT and POST_INSTALL_SCRIPT properties are the old way to specify CMake scripts to run before and after installing a target.  They are used only when the old INSTALL_TARGETS command is used to install the target.  Use the INSTALL command instead.</para>
    <para id="prop_tgt_PREFIX"><sect2><title>PREFIX</title></sect2> What comes before the library name.</para>

    <para>The PRE_INSTALL_SCRIPT and POST_INSTALL_SCRIPT properties are the old way to specify CMake scripts to run before and after installing a target.  They are used only when the old INSTALL_TARGETS command is used to install the target.  Use the INSTALL command instead.</para>
    <para id="prop_tgt_PRIVATE_HEADER"><sect2><title>PRIVATE_HEADER</title></sect2> Specify private header files in a FRAMEWORK shared library target.</para>

    <para>Shared library targets marked with the FRAMEWORK property generate frameworks on OS X and normal shared libraries on other platforms.  This property may be set to a list of header files to be placed in the PrivateHeaders directory inside the framework folder.  On non-Apple platforms these headers may be installed using the PRIVATE_HEADER option to the install(TARGETS) command.</para>
    <para id="prop_tgt_PROJECT_LABEL"><sect2><title>PROJECT_LABEL</title></sect2> Change the name of a target in an IDE.</para>

    <para>Can be used to change the name of the target in an IDE like visual stuido. </para>

    <para>Shared library targets marked with the FRAMEWORK property generate frameworks on OS X and normal shared libraries on other platforms.  This property may be set to a list of header files to be placed in the Headers directory inside the framework folder.  On non-Apple platforms these headers may be installed using the PUBLIC_HEADER option to the install(TARGETS) command.</para>
    <para id="prop_tgt_RESOURCE"><sect2><title>RESOURCE</title></sect2> Specify resource files in a FRAMEWORK shared library target.</para>

    <para>Shared library targets marked with the FRAMEWORK property generate frameworks on OS X and normal shared libraries on other platforms.  This property may be set to a list of files to be placed in the Resources directory inside the framework folder.  On non-Apple platforms these files may be installed using the RESOURCE option to the install(TARGETS) command.</para>
    <para id="prop_tgt_RUNTIME_OUTPUT_DIRECTORY"><sect2><title>RUNTIME_OUTPUT_DIRECTORY</title></sect2> Output directory in which to build RUNTIME target files.</para>

    <para>This property specifies the directory into which runtime target files should be built. There are three kinds of target files that may be built: archive, library, and runtime.  Executables are always treated as runtime targets. Static libraries are always treated as archive targets. Module libraries are always treated as library targets. For non-DLL platforms shared libraries are treated as library targets. For DLL platforms the DLL part of a shared library is treated as a runtime target and the corresponding import library is treated as an archive target. All Windows-based systems including Cygwin are DLL platforms. This property is initialized by the value of the variable CMAKE_RUNTIME_OUTPUT_DIRECTORY if it is set when a target is created.</para>

    <para>SKIP_BUILD_RPATH is a boolean specifying whether to skip automatic generation of an rpath allowing the target to run from the build tree. </para>
    <para id="prop_tgt_SOURCES"><sect2><title>SOURCES</title></sect2> Source names specified for a target.</para>

    <para>Read-only list of sources specified for a target.  The names returned are suitable for passing to the set_source_files_properties command.</para>
    <para id="prop_tgt_SOVERSION"><sect2><title>SOVERSION</title></sect2> What version number is this target.</para>

    <para>For shared libraries VERSION and SOVERSION can be used to specify the build version and api version respectively. When building or installing appropriate symlinks are created if the platform supports symlinks and the linker supports so-names. If only one of both is specified the missing is assumed to have the same version number. For shared libraries and executables on Windows the VERSION attribute is parsed to extract a "major.minor" version number. These numbers are used as the image version of the binary. </para>

    <para id="prop_sf_ABSTRACT"><sect2><title>ABSTRACT</title></sect2> Is this source file an abstract class.</para>

    <para>A property on a source file that indicates if the source file represents a class that is abstract. This only makes sense for languages that have a notion of an abstract class and it is only used by some tools that wrap classes into other languages.</para>
    <para id="prop_sf_COMPILE_DEFINITIONS"><sect2><title>COMPILE_DEFINITIONS</title></sect2> Preprocessor definitions for compiling a source file.</para>

    <para>The COMPILE_DEFINITIONS property may be set to a list of preprocessor definitions using the syntax VAR or VAR=value.  Function-style definitions are not supported.  CMake will automatically escape the value correctly for the native build system (note that CMake language syntax may require escapes to specify some values).  This property may be set on a per-configuration basis using the name COMPILE_DEFINITIONS_&lt;CONFIG&gt; where &lt;CONFIG&gt; is an upper-case name (ex. "COMPILE_DEFINITIONS_DEBUG").
</para><para>CMake will automatically drop some definitions that are not supported by the native build tool.  The VS6 IDE does not support definitions with values (but NMake does).  Xcode does not support per-configuration definitions on source files.
</para><para>Dislaimer: Most native build tools have poor support for escaping certain values.  CMake has work-arounds for many cases but some values may just not be possible to pass correctly.  If a value does not seem to be escaped correctly, do not attempt to work-around the problem by adding escape sequences to the value.  Your work-around may break in a future version of CMake that has improved escape support.  Instead consider defining the macro in a (configured) header file.  Then report the limitation.</para>
    <para id="prop_sf_COMPILE_DEFINITIONS_&lt;CONFIG&gt;"><sect2><title>COMPILE_DEFINITIONS_&lt;CONFIG&gt;</title></sect2> Per-configuration preprocessor definitions on a source file.</para>

    <para id="prop_sf_EXTERNAL_OBJECT"><sect2><title>EXTERNAL_OBJECT</title></sect2> If set to true then this is an object file.</para>

    <para>If this property is set to true then the source file is really an object file and should not be compiled.  It will still be linked into the target though.</para>
    <para id="prop_sf_GENERATED"><sect2><title>GENERATED</title></sect2> Is this source file generated as part of the build process.</para>

    <para>If a source file is generated by the build process CMake will handle it differently in temrs of dependency checking etc. Otherwise having a non-existent source file could create problems.</para>
    <para id="prop_sf_HEADER_FILE_ONLY"><sect2><title>HEADER_FILE_ONLY</title></sect2> Is this source file only a header file.</para>

    <para>A property on a source file that indicates if the source file is a header file with no associated implementation. This is set automatically based on the file extension and is used by CMake to determine is certain dependency information should be computed.</para>
    <para id="prop_sf_KEEP_EXTENSION"><sect2><title>KEEP_EXTENSION</title></sect2> Make the output file have the same extension as the source file.</para>

    <para>If this property is set then the file extension of the output file will be the same as that of the source file. Normally the output file extension is computed based on the language of the source file, for example .cxx will go to a .o extension.</para>
    <para id="prop_sf_LANGUAGE"><sect2><title>LANGUAGE</title></sect2> What programming language is the file.</para>

    <para>A property that can be set to indicate what programming language the source file is. If it is not set the language is determined based on the file extension. Typical values are CXX C etc.</para>
    <para id="prop_sf_LOCATION"><sect2><title>LOCATION</title></sect2> The full path to a source file.</para>

    <para>A read only property on a SOURCE FILE that contains the full path to the source file.</para>
    <para id="prop_sf_MACOSX_PACKAGE_LOCATION"><sect2><title>MACOSX_PACKAGE_LOCATION</title></sect2> Place a source file inside a Mac OS X bundle or framework.</para>

    <para>Executable targets with the MACOSX_BUNDLE property set are built as Mac OS X application bundles on Apple platforms.  Shared library targets with the FRAMEWORK property set are built as Mac OS X frameworks on Apple platforms.  Source files listed in the target with this property set will be copied to a directory inside the bundle or framework content folder specified by the property value.  For bundles the content folder is "&lt;name&gt;.app/Contents".  For frameworks the content folder is "&lt;name&gt;.framework/Versions/&lt;version&gt;".  See the PUBLIC_HEADER, PRIVATE_HEADER, and RESOURCE target properties for specifying files meant for Headers, PrivateHeadres, or Resources directories.</para>
    <para id="prop_sf_OBJECT_DEPENDS"><sect2><title>OBJECT_DEPENDS</title></sect2> Additional files on which a compiled object file depends.</para>

    <para>Specifies a semicolon-separated list of full-paths to files on which any object files compiled from this source file depend.  An object file will be recompiled if any of the named files is newer than it.
</para><para>This property need not be used to specify the dependency of a source file on a generated header file that it includes.  Although the property was originally introduced for this purpose, it is no longer necessary.  If the generated header file is created by a custom command in the same target as the source file, the automatic dependency scanning process will recognize the dependency.  If the generated header file is created by another target, an inter-target dependency should be created with the add_dependencies command (if one does not already exist due to linking relationships).</para>
    <para id="prop_sf_OBJECT_OUTPUTS"><sect2><title>OBJECT_OUTPUTS</title></sect2> Additional outputs for a Makefile rule.</para>

    <para>Additional outputs created by compilation of this source file. If any of these outputs is missing the object will be recompiled. This is supported only on Makefile generators and will be ignored on other generators.</para>
    <para id="prop_sf_SYMBOLIC"><sect2><title>SYMBOLIC</title></sect2> Is this just a name for a rule.</para>

    <para>If SYMBOLIC (boolean) is set to true the build system will be informed that the source file is not actually created on disk but instead used as a symbolic name for a build rule.</para>
    <para id="prop_sf_WRAP_EXCLUDE"><sect2><title>WRAP_EXCLUDE</title></sect2> Exclude this source file from any code wrapping techniques.</para>

    <para>Some packages can wrap source files into alternate languages to provide additional functionality. For example, C++ code can be wrapped into Java or Python etc using SWIG etc. If WRAP_EXCLUDE is set to true (1 etc) that indicates then this source file should not be wrapped.</para>

<literallayout>  CMake Compatibility Listfile Commands - Obsolete commands supported by CMake for compatibility.</literallayout>
    
<para>This is the documentation for now obsolete listfile commands from previous CMake versions, which are still supported for compatibility reasons. You should instead use the newer, faster and shinier new commands. ;-)</para>
    <para id="command_build_name"><sect2><title>build_name</title></sect2> Deprecated.  Use ${CMAKE_SYSTEM} and ${CMAKE_CXX_COMPILER} instead.</para>

    <literallayout>  build_name(variable)
</literallayout>
    <para>Sets the specified variable to a string representing the platform and compiler settings.  These values are now available through the CMAKE_SYSTEM and CMAKE_CXX_COMPILER variables.</para>
    <para id="command_exec_program"><sect2><title>exec_program</title></sect2> Deprecated.  Use the execute_process() command instead.</para>

    <para>Run an executable program during the processing of the CMakeList.txt file.
</para><literallayout>  exec_program(Executable [directory in which to run]
               [ARGS &lt;arguments to executable&gt;]
               [OUTPUT_VARIABLE &lt;var&gt;]
               [RETURN_VALUE &lt;var&gt;])
</literallayout>
    <para>The executable is run in the optionally specified directory.  The executable can include arguments if it is double quoted, but it is better to use the optional ARGS argument to specify arguments to the program.   This is because cmake will then be able to escape spaces in the executable path.  An optional argument OUTPUT_VARIABLE specifies a variable in which to store the output. To capture the return value of the execution, provide a RETURN_VALUE. If OUTPUT_VARIABLE is specified, then no output will go to the stdout/stderr of the console running cmake.
</para>
    <para id="command_export_library_dependencies"><sect2><title>export_library_dependencies</title></sect2> Deprecated.  Use INSTALL(EXPORT) or EXPORT command.</para>

    <para>This command generates an old-style library dependencies file.  Projects requiring CMake 2.6 or later should not use the command.  Use instead the install(EXPORT) command to help export targets from an installation tree and the export() command to export targets from a build tree.
</para><para>The old-style library dependencies file does not take into account per-configuration names of libraries or the LINK_INTERFACE_LIBRARIES target property.
</para><literallayout>  export_library_dependencies(&lt;file&gt; [APPEND])
</literallayout>
    <para>Create a file named &lt;file&gt; that can be included into a CMake listfile with the INCLUDE command.  The file will contain a number of SET commands that will set all the variables needed for library dependency information.  This should be the last command in the top level CMakeLists.txt file of the project.  If the APPEND option is specified, the SET commands will be appended to the given file instead of replacing it.</para>
    <para id="command_install_files"><sect2><title>install_files</title></sect2> Deprecated.  Use the install(FILES ) command instead.</para>

    <para>This command has been superceded by the install command.  It is provided for compatibility with older CMake code.  The FILES form is directly replaced by the FILES form of the install command.  The regexp form can be expressed more clearly using the GLOB form of the file command.
</para><literallayout>  install_files(&lt;dir&gt; extension file file ...)
</literallayout>
    <para>Create rules to install the listed files with the given extension into the given directory.  Only files existing in the current source tree or its corresponding location in the binary tree may be listed.  If a file specified already has an extension, that extension will be removed first.  This is useful for providing lists of source files such as foo.cxx when you want the corresponding foo.h to be installed. A typical extension is '.h'.
</para><literallayout>  install_files(&lt;dir&gt; regexp)
</literallayout>
    <para>Any files in the current source directory that match the regular expression will be installed.
</para><literallayout>  install_files(&lt;dir&gt; FILES file file ...)
</literallayout>
    <para>Any files listed after the FILES keyword will be installed explicitly from the names given.  Full paths are allowed in this form.
</para><para>The directory &lt;dir&gt; is relative to the installation prefix, which is stored in the variable CMAKE_INSTALL_PREFIX.</para>
    <para id="command_install_programs"><sect2><title>install_programs</title></sect2> Deprecated. Use the install(PROGRAMS ) command instead.</para>

    <para>This command has been superceded by the install command.  It is provided for compatibility with older CMake code.  The FILES form is directly replaced by the PROGRAMS form of the INSTALL command.  The regexp form can be expressed more clearly using the GLOB form of the FILE command.
</para><literallayout>  install_programs(&lt;dir&gt; file1 file2 [file3 ...])
  install_programs(&lt;dir&gt; FILES file1 [file2 ...])
</literallayout>
    <para>Create rules to install the listed programs into the given directory. Use the FILES argument to guarantee that the file list version of the command will be used even when there is only one argument.
</para><literallayout>  install_programs(&lt;dir&gt; regexp)
</literallayout>
    <para>In the second form any program in the current source directory that matches the regular expression will be installed.
</para><para>This command is intended to install programs that are not built by cmake, such as shell scripts.  See the TARGETS form of the INSTALL command to create installation rules for targets built by cmake.
</para><para>The directory &lt;dir&gt; is relative to the installation prefix, which is stored in the variable CMAKE_INSTALL_PREFIX.</para>
    <para id="command_install_targets"><sect2><title>install_targets</title></sect2> Deprecated. Use the install(TARGETS )  command instead.</para>

    <para>This command has been superceded by the install command.  It is provided for compatibility with older CMake code.
</para><literallayout>  install_targets(&lt;dir&gt; [RUNTIME_DIRECTORY dir] target target)
</literallayout>
    <para>Create rules to install the listed targets into the given directory.  The directory &lt;dir&gt; is relative to the installation prefix, which is stored in the variable CMAKE_INSTALL_PREFIX. If RUNTIME_DIRECTORY is specified, then on systems with special runtime files (Windows DLL), the files will be copied to that directory.</para>
    <para id="command_link_libraries"><sect2><title>link_libraries</title></sect2> Deprecated. Use the target_link_libraries() command instead.</para>

    <para>Link libraries to all targets added later.
</para><literallayout>  link_libraries(library1 &lt;debug | optimized&gt; library2 ...)
</literallayout>
    <para>Specify a list of libraries to be linked into any following targets (typically added with the add_executable or add_library calls).  This command is passed down to all subdirectories.  The debug and optimized strings may be used to indicate that the next library listed is to be used only for that specific type of build.</para>
    <para id="command_make_directory"><sect2><title>make_directory</title></sect2> Deprecated. Use the file(MAKE_DIRECTORY ) command instead.</para>

    <literallayout>  make_directory(directory)
</literallayout>
    <para>Creates the specified directory.  Full paths should be given.  Any parent directories that do not exist will also be created.  Use with care.</para>
    <para id="command_remove"><sect2><title>remove</title></sect2> Deprecated. Use the list(REMOVE_ITEM ) command instead.</para>

    <literallayout>  remove(VAR VALUE VALUE ...)
</literallayout>
    <para>Removes VALUE from the variable VAR.  This is typically used to remove entries from a vector (e.g. semicolon separated list).  VALUE is expanded.</para>
    <para id="command_subdir_depends"><sect2><title>subdir_depends</title></sect2> Deprecated.  Does nothing.</para>

    <literallayout>  subdir_depends(subdir dep1 dep2 ...)
</literallayout>
    <para>Does not do anything.  This command used to help projects order parallel builds correctly.  This functionality is now automatic.</para>
    <para id="command_subdirs"><sect2><title>subdirs</title></sect2> Deprecated. Use the add_subdirectory() command instead.</para>

    <para>Add a list of subdirectories to the build.
</para><literallayout>  subdirs(dir1 dir2 ...[EXCLUDE_FROM_ALL exclude_dir1 exclude_dir2 ...] [PREORDER] )
</literallayout>
    <para>Add a list of subdirectories to the build. The add_subdirectory command should be used instead of subdirs although subdirs will still work. This will cause any CMakeLists.txt files in the sub directories to be processed by CMake.  Any directories after the PREORDER flag are traversed first by makefile builds, the PREORDER flag has no effect on IDE projects.  Any directories after the EXCLUDE_FROM_ALL marker will not be included in the top level makefile or project file. This is useful for having CMake create makefiles or projects for a set of examples in a project. You would want CMake to generate makefiles or project files for all the examples at the same time, but you would not want them to show up in the top level project or be built each time make is run from the top.</para>
    <para id="command_use_mangled_mesa"><sect2><title>use_mangled_mesa</title></sect2> Copy mesa headers for use in combination with system GL.</para>

    <literallayout>  use_mangled_mesa(PATH_TO_MESA OUTPUT_DIRECTORY)
</literallayout>
    <para>The path to mesa includes, should contain gl_mangle.h.  The mesa headers are copied to the specified output directory.  This allows mangled mesa headers to override other GL headers by being added to the include directory path earlier.</para>
    <para id="command_utility_source"><sect2><title>utility_source</title></sect2> Specify the source tree of a third-party utility.</para>

    <literallayout>  utility_source(cache_entry executable_name
                 path_to_source [file1 file2 ...])
</literallayout>
    <para>When a third-party utility's source is included in the distribution, this command specifies its location and name.  The cache entry will not be set unless the path_to_source and all listed files exist.  It is assumed that the source tree of the utility will have been built before it is needed.
</para><para>When cross compiling CMake will print a warning if a utility_source() command is executed, because in many cases it is used to build an executable which is executed later on. This doesn't work when cross compiling, since the executable can run only on their target platform. So in this case the cache entry has to be adjusted manually so it points to an executable which is runnable on the build host.</para>
    <para id="command_variable_requires"><sect2><title>variable_requires</title></sect2> Deprecated. Use the if() command instead.</para>

    <para>Assert satisfaction of an option's required variables.
</para><literallayout>  variable_requires(TEST_VARIABLE RESULT_VARIABLE
                    REQUIRED_VARIABLE1
                    REQUIRED_VARIABLE2 ...)
</literallayout>
    <para>The first argument (TEST_VARIABLE) is the name of the variable to be tested, if that variable is false nothing else is done. If TEST_VARIABLE is true, then the next argument (RESULT_VARIABLE) is a variable that is set to true if all the required variables are set. The rest of the arguments are variables that must be true or not set to NOTFOUND to avoid an error.  If any are not true, an error is reported.</para>
    <para id="command_write_file"><sect2><title>write_file</title></sect2> Deprecated. Use the file(WRITE ) command instead.</para>

    <literallayout>  write_file(filename "message to write"... [APPEND])
</literallayout>
    <para>The first argument is the file name, the rest of the arguments are messages to write. If the argument APPEND is specified, then the message will be appended.
</para><para>NOTE 1: file(WRITE ... and file(APPEND ... do exactly the same as this one but add some more functionality.
</para><para>NOTE 2: When using write_file the produced file cannot be used as an input to CMake (CONFIGURE_FILE, source file ...) because it will lead to an infinite loop. Use configure_file if you want to generate input files to CMake.</para>

    <para id="module_CPack"><sect2><title>CPack</title></sect2> Build binary and source package installers</para>

    <para>
</para><para>The CPack module generates binary and source installers in a variety of formats using the cpack program. Inclusion of the CPack module adds two new targets to the resulting makefiles, package and package_source, which build the binary and source installers, respectively. The generated binary installers contain everything installed via CMake's INSTALL command (and the deprecated INSTALL_FILES, INSTALL_PROGRAMS, and INSTALL_TARGETS commands).
</para><para>For certain kinds of binary installers (including the graphical installers on Mac OS X and Windows), CPack generates installers that allow users to select individual application components to install. The contents of each of the components are identified by the COMPONENT argument of CMake's INSTALL command. These components can be annotated with user-friendly names and descriptions, inter-component dependencies, etc., and grouped in various ways to customize the resulting installer. See the cpack_add_* commands, described below, for more information about component-specific installations.
</para><para>Before including the CPack module, there are a variety of variables that can be set to customize the resulting installers. The most commonly-used variables are:
</para><literallayout>   CPACK_PACKAGE_NAME - The name of the package (or application). If
   not specified, defaults to the project name.
</literallayout>
    <para>

   project (only a few words).
</literallayout>
    <para>

   so this change is compatible).
</literallayout>
    <para>
</para><literallayout>   CPACK_SOURCE_GENERATOR - List of generators used for the source
   packages. As with CPACK_GENERATOR, if this is not specified then

   installers that download component son-the-fly for Mac OS X 10.5
   or newer. If left blank, this value will be set to the minimum
   version of Mac OS X that supports the requested features. Set this
   variable to some value (e.g., 10.4) only if you want to guarantee
   that your installer will work on that version of Mac OS X, and
   don't mind missing extra features available in the installer
   shipping with later versions of Mac OS X.

</para><literallayout>   The cpack_configure_downloads command configures installation-time
   downloads of selected components. For each downloadable component,
   CPack will create an archive containing the contents of that
   component, which should be uploaded to the given site. When the
   user selects that component for installation, the installer will
   download and extract the component in place. This feature is
   useful for creating small installers that only download the
   requested components, saving bandwidth. Additionally, the
   installers are small enough that they will be installed as part of
   the normal installation process, and the "Change" button in
   Windows Add/Remove Programs control panel will allow one to add or
   remove parts of the application after the original
   installation. On Windows, the downloaded-components functionality
   requires the ZipDLL plug-in for NSIS, available at:

   inside the CMake binary directory to store the generated archives.

</para><literallayout>   The ALL flag indicates that all components be downloaded. Otherwise, only 
   those components explicitly marked as DOWNLOADED or that have a specified 
   ARCHIVE_FILE will be downloaded. Additionally, the ALL option implies
   ADD_REMOVE (unless NO_ADD_REMOVE is specified).
</literallayout>
    <para>
</para><literallayout>   ADD_REMOVE indicates that CPack should install a copy of the installer
   that can be called from Windows' Add/Remove Programs dialog (via the 
   "Modify" button) to change the set of installed components. NO_ADD_REMOVE
   turns off this behavior. This option is ignored on Mac OS X.

      target_link_libraries(foo ${Boost_LIBRARIES})
   endif()
</literallayout>
    <para>
</para><para>
</para><para>The components list needs to contain actual names of boost libraries only, such as "date_time" for "libboost_date_time".  If you're using parts of Boost that contain header files only (e.g. foreach) you do not need to specify COMPONENTS.
</para><para>You should provide a minimum version number that should be used. If you provide this  version number and specify the REQUIRED attribute, this module will fail if it can't find the specified or a later version. If you specify a version number this is automatically put into the considered list of version numbers and thus doesn't need to be specified in the Boost_ADDITIONAL_VERSIONS variable (see below).
</para><para>NOTE for Visual Studio Users:
</para><literallayout>     Automatic linking is used on MSVC &amp; Borland compilers by default when
     #including things in Boost.  It's important to note that setting
     Boost_USE_STATIC_LIBS to OFF is NOT enough to get you dynamic linking,
     should you need this feature.  Automatic linking typically uses static
     libraries with a few exceptions (Boost.Python is one).
</literallayout>
    <para>
</para><literallayout>     Please see the section below near Boost_LIB_DIAGNOSTIC_DEFINITIONS for
     more details.  Adding a TARGET_LINK_LIBRARIES() as shown in the example
     above appears to cause VS to link dynamically if Boost_USE_STATIC_LIBS
     gets set to OFF.  It is suggested you avoid automatic linking since it
     will make your application less portable.
</literallayout>
    <para>
</para><para>=========== The mess that is Boost_ADDITIONAL_VERSIONS (sorry?) ============
</para><para>OK, so the Boost_ADDITIONAL_VERSIONS variable can be used to specify a list of boost version numbers that should be taken into account when searching for Boost. Unfortunately boost puts the version number into the actual filename for the libraries, so this variable will certainly be needed in the future when new Boost versions are released.
</para><para>Currently this module searches for the following version numbers: 1.33, 1.33.0, 1.33.1, 1.34, 1.34.0, 1.34.1, 1.35, 1.35.0, 1.35.1, 1.36, 1.36.0, 1.36.1, 1.37, 1.37.0, 1.38, 1.38.0
</para><para>NOTE: If you add a new major 1.x version in Boost_ADDITIONAL_VERSIONS you should add both 1.x and 1.x.0 as shown above.  Official Boost include directories omit the 3rd version number from include paths if it is 0 although not all binary Boost releases do so.
</para><para>SET(Boost_ADDITIONAL_VERSIONS "0.99" "0.99.0" "1.78" "1.78.0")
</para><para>============================================================================
</para><para>Variables used by this module, they can change the default behaviour and need to be set before calling find_package:
</para><literallayout>  Boost_USE_MULTITHREADED       Can be set to OFF to use the non-multithreaded
                                boost libraries.  If not specified, defaults
                                to ON.
</literallayout>
    <para>
</para><literallayout>  Boost_USE_STATIC_LIBS         Can be set to ON to force the use of the static

    <para>
</para><para>The Message Passing Interface (MPI) is a library used to write high-performance parallel applications that use message passing, and is typically deployed on a cluster. MPI is a standard interface (defined by the MPI forum) for which many implementations are available. All of these implementations have somewhat different compilation approaches (different include paths, libraries to link against, etc.), and this module tries to smooth out those differences.
</para><para>This module will set the following variables:
</para><literallayout>   MPI_FOUND                  TRUE if we have found MPI
   MPI_COMPILE_FLAGS          Compilation flags for MPI programs

</literallayout>
    <para>
</para><para>This module will attempt to auto-detect these settings, first by looking for a MPI compiler, which many MPI implementations provide as a pass-through to the native compiler to simplify the compilation of MPI programs. The MPI compiler is stored in the cache variable MPI_COMPILER, and will attempt to look for commonly-named drivers mpic++, mpicxx, mpiCC, or mpicc. If the compiler driver is found and recognized, it will be used to set all of the module variables. To skip this auto-detection, set MPI_LIBRARY and MPI_INCLUDE_PATH in the CMake cache.
</para><para>If no compiler driver is found or the compiler driver is not recognized, this module will then search for common include paths and library names to try to detect MPI. 
</para><para>If CMake initially finds a different MPI than was intended, and you want to use the MPI compiler auto-detection for a different MPI implementation, set MPI_COMPILER to the MPI compiler driver you want to use (e.g., mpicxx) and then set MPI_LIBRARY to the string MPI_LIBRARY-NOTFOUND. When you re-configure, auto-detection of MPI will run again with the newly-specified MPI_COMPILER.
</para><para>When using MPIEXEC to execute MPI applications, you should typically use all of the MPIEXEC flags as follows:
</para><literallayout>   ${MPIEXEC} ${MPIEXEC_NUMPROC_FLAG} PROCS ${MPIEXEC_PREFLAGS} EXECUTABLE
     ${MPIEXEC_POSTFLAGS} ARGS
</literallayout>

    <para>FIND_PACKAGE_HANDLE_STANDARD_ARGS(NAME (DEFAULT_MSG|"Custom failure message") VAR1 ... )
</para><literallayout>    This macro is intended to be used in FindXXX.cmake modules files.
    It handles the REQUIRED and QUIET argument to FIND_PACKAGE() and
    it also sets the &lt;UPPERCASED_NAME&gt;_FOUND variable.
    The package is found if all variables listed are TRUE.
    Example:
</literallayout>
    <para>
</para><literallayout>    FIND_PACKAGE_HANDLE_STANDARD_ARGS(LibXml2 DEFAULT_MSG LIBXML2_LIBRARIES LIBXML2_INCLUDE_DIR)
</literallayout>
    <para>
</para><literallayout>    LibXml2 is considered to be found, if both LIBXML2_LIBRARIES and 
    LIBXML2_INCLUDE_DIR are valid. Then also LIBXML2_FOUND is set to TRUE.
    If it is not found and REQUIRED was used, it fails with FATAL_ERROR, 
    independent whether QUIET was used or not.
    If it is found, the location is reported using the VAR1 argument, so 
    here a message "Found LibXml2: /usr/lib/libxml2.so" will be printed out.
    If the second argument is DEFAULT_MSG, the message in the failure case will 
    be "Could NOT find LibXml2", if you don't like this message you can specify
    your own custom failure message there.

        So if you have the files foo.h and foo.cpp, and in foo.h a 
        a class uses the Q_OBJECT macro, moc has to run on it. If you don't
        want to use QT4_WRAP_CPP() (which is reliable and mature), you can insert
        #include "foo.moc"
        in foo.cpp and then give foo.cpp as argument to QT4_AUTOMOC(). This will the
        scan all listed files at cmake-time for such included moc files and if it finds
        them cause a rule to be generated to run moc at build time on the 
        accompanying header file foo.h.
        If a source file has the SKIP_AUTOMOC property set it will be ignored by this macro.

                               "wx/setup.h"; possibly empty for unices.
  wxWidgets_LIBRARIES        - Path to the wxWidgets libraries.
  wxWidgets_LIBRARY_DIRS     - compile time link dirs, useful for
                               rpath on UNIX. Typically an empty string

    <para id="policy_CMP0000"><sect2><title>CMP0000</title></sect2> A minimum required CMake version must be specified.</para>

    <para>CMake requires that projects specify the version of CMake to which they have been written.  This policy has been put in place so users trying to build the project may be told when they need to update their CMake.  Specifying a version also helps the project build with CMake versions newer than that specified.  Use the cmake_minimum_required command at the top of your main  CMakeLists.txt file:
</para><literallayout>  cmake_minimum_required(VERSION &lt;major&gt;.&lt;minor&gt;)
</literallayout>
    <para>where "&lt;major&gt;.&lt;minor&gt;" is the version of CMake you want to support (such as "2.6").  The command will ensure that at least the given version of CMake is running and help newer versions be compatible with the project.  See documentation of cmake_minimum_required for details.
</para><para>Note that the command invocation must appear in the CMakeLists.txt file itself; a call in an included file is not sufficient.  However, the cmake_policy command may be called to set policy CMP0000 to OLD or NEW behavior explicitly.  The OLD behavior is to silently ignore the missing invocation.  The NEW behavior is to issue an error instead of a warning.  An included file may set CMP0000 explicitly to affect how this policy is enforced for the main CMakeLists.txt file.
</para><para>This policy was introduced in CMake version 2.6.0.</para>
    <para id="policy_CMP0001"><sect2><title>CMP0001</title></sect2> CMAKE_BACKWARDS_COMPATIBILITY should no longer be used.</para>

    <para>The OLD behavior is to check CMAKE_BACKWARDS_COMPATIBILITY and present it to the user.  The NEW behavior is to ignore CMAKE_BACKWARDS_COMPATIBILITY completely.
</para><para>In CMake 2.4 and below the variable CMAKE_BACKWARDS_COMPATIBILITY was used to request compatibility with earlier versions of CMake.  In CMake 2.6 and above all compatibility issues are handled by policies and the cmake_policy command.  However, CMake must still check CMAKE_BACKWARDS_COMPATIBILITY for projects written for CMake 2.4 and below.
</para><para>This policy was introduced in CMake version 2.6.0.  CMake version 2.6 warns when the policy is not set and uses OLD behavior.  Use the cmake_policy command to set it to OLD or NEW explicitly.</para>
    <para id="policy_CMP0002"><sect2><title>CMP0002</title></sect2> Logical target names must be globally unique.</para>

    <para>Targets names created with add_executable, add_library, or add_custom_target are logical build target names.  Logical target names must be globally unique because:
</para><literallayout>  - Unique names may be referenced unambiguously both in CMake
    code and on make tool command lines.
  - Logical names are used by Xcode and VS IDE generators
    to produce meaningful project names for the targets.
</literallayout>
    <para>The logical name of executable and library targets does not have to correspond to the physical file names built.  Consider using the OUTPUT_NAME target property to create two targets with the same physical name while keeping logical names distinct.  Custom targets must simply have globally unique names (unless one uses the global property ALLOW_DUPLICATE_CUSTOM_TARGETS with a Makefiles generator).
</para><para>This policy was introduced in CMake version 2.6.0.  CMake version 2.6 warns when the policy is not set and uses OLD behavior.  Use the cmake_policy command to set it to OLD or NEW explicitly.</para>
    <para id="policy_CMP0003"><sect2><title>CMP0003</title></sect2> Libraries linked via full path no longer produce linker search paths.</para>

    <para>This policy affects how libraries whose full paths are NOT known are found at link time, but was created due to a change in how CMake deals with libraries whose full paths are known.  Consider the code
</para><literallayout>  target_link_libraries(myexe /path/to/libA.so)
</literallayout>
    <para>CMake 2.4 and below implemented linking to libraries whose full paths are known by splitting them on the link line into separate components consisting of the linker search path and the library name.  The example code might have produced something like
</para><literallayout>  ... -L/path/to -lA ...
</literallayout>
    <para>in order to link to library A.  An analysis was performed to order multiple link directories such that the linker would find library A in the desired location, but there are cases in which this does not work.  CMake versions 2.6 and above use the more reliable approach of passing the full path to libraries directly to the linker in most cases.  The example code now produces something like
</para><literallayout>  ... /path/to/libA.so ....
</literallayout>
    <para>Unfortunately this change can break code like
</para><literallayout>  target_link_libraries(myexe /path/to/libA.so B)
</literallayout>
    <para>where "B" is meant to find "/path/to/libB.so".  This code is wrong because the user is asking the linker to find library B but has not provided a linker search path (which may be added with the link_directories command).  However, with the old linking implementation the code would work accidentally because the linker search path added for library A allowed library B to be found.
</para><para>In order to support projects depending on linker search paths added by linking to libraries with known full paths, the OLD behavior for this policy will add the linker search paths even though they are not needed for their own libraries.  When this policy is set to OLD, CMake will produce a link line such as
</para><literallayout>  ... -L/path/to /path/to/libA.so -lB ...
</literallayout>
    <para>which will allow library B to be found as it was previously.  When this policy is set to NEW, CMake will produce a link line such as
</para><literallayout>  ... /path/to/libA.so -lB ...
</literallayout>
    <para>which more accurately matches what the project specified.
</para><para>The setting for this policy used when generating the link line is that in effect when the target is created by an add_executable or add_library command.  For the example described above, the code
</para><literallayout>  cmake_policy(SET CMP0003 OLD) # or cmake_policy(VERSION 2.4)
  add_executable(myexe myexe.c)
  target_link_libraries(myexe /path/to/libA.so B)
</literallayout>
    <para>will work and suppress the warning for this policy.  It may also be updated to work with the corrected linking approach:
</para><literallayout>  cmake_policy(SET CMP0003 NEW) # or cmake_policy(VERSION 2.6)
  link_directories(/path/to) # needed to find library B
  add_executable(myexe myexe.c)
  target_link_libraries(myexe /path/to/libA.so B)
</literallayout>
    <para>Even better, library B may be specified with a full path:
</para><literallayout>  add_executable(myexe myexe.c)
  target_link_libraries(myexe /path/to/libA.so /path/to/libB.so)
</literallayout>
    <para>When all items on the link line have known paths CMake does not check this policy so it has no effect.
</para><para>Note that the warning for this policy will be issued for at most one target.  This avoids flooding users with messages for every target when setting the policy once will probably fix all targets.
</para><para>This policy was introduced in CMake version 2.6.0.  CMake version 2.6 warns when the policy is not set and uses OLD behavior.  Use the cmake_policy command to set it to OLD or NEW explicitly.</para>
    <para id="policy_CMP0004"><sect2><title>CMP0004</title></sect2> Libraries linked may not have leading or trailing whitespace.</para>

    <para>CMake versions 2.4 and below silently removed leading and trailing whitespace from libraries linked with code like
</para><literallayout>  target_link_libraries(myexe " A ")
</literallayout>
    <para>This could lead to subtle errors in user projects.
</para><para>The OLD behavior for this policy is to silently remove leading and trailing whitespace.  The NEW behavior for this policy is to diagnose the existence of such whitespace as an error.  The setting for this policy used when checking the library names is that in effect when the target is created by an add_executable or add_library command.

    <para id="policy_CMP0005"><sect2><title>CMP0005</title></sect2> Preprocessor definition values are now escaped automatically.</para>

    <para>This policy determines whether or not CMake should generate escaped preprocessor definition values added via add_definitions.  CMake versions 2.4 and below assumed that only trivial values would be given for macros in add_definitions calls.  It did not attempt to escape non-trivial values such as string literals in generated build rules.  CMake versions 2.6 and above support escaping of most values, but cannot assume the user has not added escapes already in an attempt to work around limitations in earlier versions.
</para><para>The OLD behavior for this policy is to place definition values given to add_definitions directly in the generated build rules without attempting to escape anything.  The NEW behavior for this policy is to generate correct escapes for all native build tools automatically.  See documentation of the COMPILE_DEFINITIONS target property for limitations of the escaping implementation.

    <para>This policy determines whether the install(TARGETS) command must be given a BUNDLE DESTINATION when asked to install a target with the MACOSX_BUNDLE property set.  CMake 2.4 and below did not distinguish application bundles from normal executables when installing targets.  CMake 2.6 provides a BUNDLE option to the install(TARGETS) command that specifies rules specific to application bundles on the Mac.  Projects should use this option when installing a target with the MACOSX_BUNDLE property set.
</para><para>The OLD behavior for this policy is to fall back to the RUNTIME DESTINATION if a BUNDLE DESTINATION is not given.  The NEW behavior for this policy is to produce an error if a bundle target is installed without a BUNDLE DESTINATION.

    <para>This policy determines whether the list command will ignore empty elements in the list. CMake 2.4 and below list commands ignored all empty elements in the list.  For example, a;b;;c would have length 3 and not 4. The OLD behavior for this policy is to ignore empty list elements. The NEW behavior for this policy is to correctly count empty elements in a list.

    <para id="policy_CMP0008"><sect2><title>CMP0008</title></sect2> Libraries linked by full-path must have a valid library file name.</para>

    <para>In CMake 2.4 and below it is possible to write code like
</para><literallayout>  target_link_libraries(myexe /full/path/to/somelib)
</literallayout>
    <para>where "somelib" is supposed to be a valid library file name such as "libsomelib.a" or "somelib.lib".  For Makefile generators this produces an error at build time because the dependency on the full path cannot be found.  For VS IDE and Xcode generators this used to work by accident because CMake would always split off the library directory and ask the linker to search for the library by name (-lsomelib or somelib.lib).  Despite the failure with Makefiles, some projects have code like this and build only with VS and/or Xcode.  This version of CMake prefers to pass the full path directly to the native build tool, which will fail in this case because it does not name a valid library file.
</para><para>This policy determines what to do with full paths that do not appear to name a valid library file.  The OLD behavior for this policy is to split the library name from the path and ask the linker to search for it.  The NEW behavior for this policy is to trust the given path and pass it directly to the native build tool unchanged.

    <para>In CMake 2.6.1 and below, FILE GLOB_RECURSE calls would follow through symlinks, sometimes coming up with unexpectedly large result sets because of symlinks to top level directories that contain hundreds of thousands of files.
</para><para>This policy determines whether or not to follow symlinks encountered during a FILE GLOB_RECURSE call. The OLD behavior for this policy is to follow the symlinks. The NEW behavior for this policy is not to follow the symlinks by default, but only if FOLLOW_SYMLINKS is given as an additional argument to the FILE command.

    <para>In CMake 2.6.2 and below, incorrect variable reference syntax such as a missing close-brace ("${FOO") was reported but did not stop processing of CMake code.  This policy determines whether a bad variable reference is an error.  The OLD behavior for this policy is to warn about the error, leave the string untouched, and continue. The NEW behavior for this policy is to report an error.

    <para>In CMake 2.6.2 and below, CMake Policy settings in scripts loaded by the include() and find_package() commands would affect the includer.  Explicit invocations of cmake_policy(PUSH) and cmake_policy(POP) were required to isolate policy changes and protect the includer.  While some scripts intend to affect the policies of their includer, most do not.  In CMake 2.6.3 and above, include() and find_package() by default PUSH and POP an entry on the policy stack around an included script, but provide a NO_POLICY_SCOPE option to disable it.  This policy determines whether or not to imply NO_POLICY_SCOPE for compatibility.  The OLD behavior for this policy is to imply NO_POLICY_SCOPE for include() and find_package() commands.  The NEW behavior for this policy is to allow the commands to do their default cmake_policy PUSH and POP.

    <para id="variable_CMAKE_OBJECT_PATH_MAX"><sect2><title>CMAKE_OBJECT_PATH_MAX</title></sect2> Maximum object file full-path length allowed by native build tools.</para>

    <para>CMake computes for every source file an object file name that is unique to the source file and deterministic with respect to the full path to the source file.  This allows multiple source files in a target to share the same name if they lie in different directories without rebuilding when one is added or removed.  However, it can produce long full paths in a few cases, so CMake shortens the path using a hashing scheme when the full path to an object file exceeds a limit.  CMake has a built-in limit for each platform that is sufficient for common tools, but some native tools may have a lower limit.  This variable may be set to specify the limit explicitly.  The value must be an integer no less than 128.</para>

<para>variables defined by cmake, that give information about the project, and cmake</para>
    <para id="variable_CMAKE_AR"><sect2><title>CMAKE_AR</title></sect2> Name of archiving tool for static libraries.</para>

    <para>This specifies name of the program that creates archive or static libraries.</para>
    <para id="variable_CMAKE_BINARY_DIR"><sect2><title>CMAKE_BINARY_DIR</title></sect2> The path to the top level of the build tree.</para>

    <para>This is the full path to the top level of the current CMake build tree. For an in-source build, this would be the same as CMAKE_SOURCE_DIR. </para>
    <para id="variable_CMAKE_BUILD_TOOL"><sect2><title>CMAKE_BUILD_TOOL</title></sect2> Tool used for the acutal build process.</para>

    <para>This variable is set to the program that will be needed to build the output of CMake.   If the generator selected was Visual Studio 6, the CMAKE_MAKE_PROGRAM will be set to msdev, for Unix makefiles it will be set to make or gmake, and for Visual Studio 7 it set to devenv.  For Nmake Makefiles the value is nmake. This can be useful for adding special flags and commands based on the final build environment. </para>
    <para id="variable_CMAKE_CACHEFILE_DIR"><sect2><title>CMAKE_CACHEFILE_DIR</title></sect2> The directory with the CMakeCache.txt file.</para>

    <para>This is the full path to the directory that has the CMakeCache.txt file in it.  This is the same as CMAKE_BINARY_DIR.</para>
    <para id="variable_CMAKE_CACHE_MAJOR_VERSION"><sect2><title>CMAKE_CACHE_MAJOR_VERSION</title></sect2> Major version of CMake used to create the CMakeCache.txt file</para>

    <para>This is stores the major version of CMake used to write a CMake cache file. It is only different when a different version of CMake is run on a previously created cache file.</para>
    <para id="variable_CMAKE_CACHE_MINOR_VERSION"><sect2><title>CMAKE_CACHE_MINOR_VERSION</title></sect2> Minor version of CMake used to create the CMakeCache.txt file</para>

    <para>This is stores the minor version of CMake used to write a CMake cache file. It is only different when a different version of CMake is run on a previously created cache file.</para>
    <para id="variable_CMAKE_CACHE_RELEASE_VERSION"><sect2><title>CMAKE_CACHE_RELEASE_VERSION</title></sect2> Release version of CMake used to create the CMakeCache.txt file</para>

    <para>This is stores the release version of CMake used to write a CMake cache file. It is only different when a different version of CMake is run on a previously created cache file.</para>
    <para id="variable_CMAKE_CFG_INTDIR"><sect2><title>CMAKE_CFG_INTDIR</title></sect2> Build time configuration directory for project.</para>

    <para>This is a variable that is used to provide developers access to the intermediate directory used by Visual Studio IDE projects.   For example, if building Debug all executables and libraries end up in a Debug directory.   On UNIX systems this variable is set to ".".  However, with Visual Studio this variable is set to $(IntDir).   $(IntDir) is expanded by the IDE only.  So this variable should only be used in custom commands that will be run during the build process.   This variable should not be used directly in a CMake command.  CMake has no way of knowing if Debug or Release will be picked by the IDE for a build type. If a program needs to know the directory it was built in, it can use CMAKE_INTDIR. CMAKE_INTDIR is a C/C++ preprocessor macro that is defined on the command line of the compiler.   If it has a value, it will be the intermediate directory used to build the file.   This way an executable or a library can find files that are located in the build directory.</para>
