cmake(1) ******** :: cmake - Cross-Platform Makefile Generator. :: cmake [options] cmake [options] 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. 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. * ``-C ``: Pre-load a script to populate the cache. 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. * ``-D :=``: Create a cmake cache entry. 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. * ``-U ``: Remove matching entries from CMake cache. 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. Use with care, you can make your CMakeCache.txt non-working. * ``-G ``: Specify a build system generator. CMake may support multiple native build systems on certain platforms. A generator is responsible for generating a particular build system. Possible generator names are specified in the Generators section. * ``-T ``: Specify toolset name if supported by generator. Some CMake generators support a toolset name to be given to the native build system to choose a compiler. This is supported only on specific generators: :: Visual Studio >= 10 Xcode >= 3.0 See native build system documentation for allowed toolset names. * ``-Wno-dev``: Suppress developer warnings. Suppress warnings that are meant for the author of the CMakeLists.txt files. * ``-Wdev``: Enable developer warnings. Enable warnings that are meant for the author of the CMakeLists.txt files. * ``-E``: CMake command mode. 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 available are: chdir, compare_files, copy, copy_directory, copy_if_different, echo, echo_append, environment, make_directory, md5sum, remove, remove_directory, rename, tar, time, touch, touch_nocreate. In addition, some platform specific commands are available. On Windows: comspec, delete_regv, write_regv. On UNIX: create_symlink. * ``-i``: Run in wizard mode. 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. * ``-L[A][H]``: List non-advanced cached variables. 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 then be changed with -D option. Changing some of the variables 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. * ``--build ``: Build a CMake-generated project binary tree. This abstracts a native build tool's command-line interface with the following options: :: = Project binary directory to be built. --target = Build instead of default targets. --config = For multi-configuration tools, choose . --clean-first = Build target 'clean' first, then build. (To clean only, use --target 'clean'.) --use-stderr = Don't merge stdout/stderr output and pass the original stdout/stderr handles to the native tool so it can use the capabilities of the calling terminal (e.g. colored output). -- = Pass remaining options to the native tool. Run cmake --build with no options for quick help. * ``-N``: View mode only. Only load the cache. Do not actually run configure and generate steps. * ``-P ``: Process script mode. 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. * ``--find-package``: Run in pkg-config like mode. Search a package using find_package() and print the resulting flags to stdout. This can be used to use cmake instead of pkg-config to find installed libraries in plain Makefile-based projects or in autoconf-based projects (via share/aclocal/cmake.m4). * ``--graphviz=[file]``: Generate graphviz of dependencies, see CMakeGraphVizOptions.cmake for more. Generate a graphviz input file that will contain all the library and executable dependencies in the project. See the documentation for CMakeGraphVizOptions.cmake for more details. * ``--system-information [file]``: Dump information about this system. Dump a wide range of information about the current system. If run from the top of a binary tree for a CMake project it will dump additional information such as the cache, log files etc. * ``--debug-trycompile``: Do not delete the try_compile build tree. Only useful on one try_compile at a time. Do not delete the files and directories created for try_compile calls. This is useful in debugging failed try_compiles. It may however change the results of the try-compiles as old junk from a previous try-compile may cause a different test to either pass or fail incorrectly. This option is best used for one try-compile at a time, and only when debugging. * ``--debug-output``: Put cmake in a debug mode. Print extra stuff during the cmake run like stack traces with message(send_error ) calls. * ``--trace``: Put cmake in trace mode. Print a trace of all calls made and from where with message(send_error ) calls. * ``--warn-uninitialized``: Warn about uninitialized values. Print a warning when an uninitialized variable is used. * ``--warn-unused-vars``: Warn about unused variables. Find variables that are declared or set, but not used. * ``--no-warn-unused-cli``: Don't warn about command line options. Don't find variables that are declared on the command line, but not used. * ``--check-system-vars``: Find problems with variable usage in system files. Normally, unused and uninitialized variables are searched for only in CMAKE_SOURCE_DIR and CMAKE_BINARY_DIR. This flag tells CMake to warn about other files as well. * ``--help-command cmd [file]``: Print help for a single command and exit. Full documentation specific to the given command is displayed.

The following generators are available on this platform: :: CMake Properties - Properties supported by CMake, the Cross-Platform Makefile Generator. This is the documentation for the properties supported by CMake. Properties can have different scopes. They can either be assigned to a source file, a directory, a target or globally to CMake. By modifying the values of properties the behaviour of the build system can be customized. :: CMake Compatibility Listfile Commands - Obsolete commands supported by CMake for compatibility. 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. ;-) The following modules are provided with CMake. They can be used with INCLUDE(ModuleName). :: CMake Modules - Modules coming with CMake, the Cross-Platform Makefile Generator. This is the documentation for the modules and scripts coming with CMake. Using these modules you can check the computer system for installed software packages, features of the compiler and the existence of headers to name just a few. variables defined by cmake, that give information about the project, and cmake Copyright 2000-2012 Kitware, Inc., Insight Software Consortium.
