-Description
-===========
-
-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.
-
-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.

-.. _`CMake Options`:
-
-Options
-=======
-
-.. include:: OPTIONS_BUILD.txt
-
-``-E <command> [<options>...]``
- See `Command-Line Tool Mode`_.
-
-``-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 <dir>``
- See `Build Tool Mode`_.
-
-``-N``
- View mode only.
-
- Only load the cache. Do not actually run configure and generate
- steps.
-
-``-P <file>``
- 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``
- See `Find-Package Tool Mode`_.
-
-``--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 information 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.
-
-``--trace-expand``
- Put cmake in trace mode.
-
- Like ``--trace``, but with variables expanded.
-
-``--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.

-Build Tool Mode
-===============
-
-CMake provides a command-line signature to build an already-generated
-project binary tree::
-
- cmake --build <dir> [<options>...] [-- <build-tool-options>...]
-
-This abstracts a native build tool's command-line interface with the
-following options:
-
-``--build <dir>``
- Project binary directory to be built. This is required and must be first.
-
-``--target <tgt>``
- Build ``<tgt>`` instead of default targets. May only be specified once.
-
-``--config <cfg>``
- For multi-configuration tools, choose configuration ``<cfg>``.
-
-``--clean-first``
- Build target ``clean`` first, then build.
- (To clean only, use ``--target clean``.)
-
-``--use-stderr``
- Ignored. Behavior is default in CMake >= 3.0.
-
-``--``
- Pass remaining options to the native tool.
-
-Run ``cmake --build`` with no options for quick help.
-
-Command-Line Tool Mode
-======================
-
-CMake provides builtin command-line tools through the signature::
-
- cmake -E <command> [<options>...]
-
-Run ``cmake -E`` or ``cmake -E help`` for a summary of commands.
-Available commands are:
-
-``chdir <dir> <cmd> [<arg>...]``
- Change the current working directory and run a command.
-
-``compare_files <file1> <file2>``
- Check if ``<file1>`` is same as ``<file2>``. If files are the same,
- then returns 0, if not it returns 1.
-
-``copy <file>... <destination>``
- Copy files to ``<destination>`` (either file or directory).
- If multiple files are specified, the ``<destination>`` must be
- directory and it must exist.
-
-``copy_directory <dir>... <destination>``
- Copy directories to ``<destination>`` directory.
- If ``<destination>`` directory does not exist it will be created.
-
-``copy_if_different <file>... <destination>``
- Copy files to ``<destination>`` (either file or directory) if
- they have changed.
- If multiple files are specified, the ``<destination>`` must be
- directory and it must exist.
-
-``echo [<string>...]``
- Displays arguments as text.
-
-``echo_append [<string>...]``
- Displays arguments as text but no new line.
-
-``env [--unset=NAME]... [NAME=VALUE]... COMMAND [ARG]...``
- Run command in a modified environment.
-
-``environment``
- Display the current environment variables.
-
-``make_directory <dir>...``
- Create ``<dir>`` directories. If necessary, create parent
- directories too. If a directory already exists it will be
- silently ignored.
-
-``md5sum <file>...``
- Create MD5 checksum of files in ``md5sum`` compatible format::
-
- 351abe79cd3800b38cdfb25d45015a15 file1.txt
- 052f86c15bbde68af55c7f7b340ab639 file2.txt
-
-``remove [-f] <file>...``
- Remove the file(s), use ``-f`` to force it. If a file does
- not exist it will be silently ignored.
-
-``remove_directory <dir>``
- Remove a directory and its contents. If a directory does
- not exist it will be silently ignored.
-
-``rename <oldname> <newname>``
- Rename a file or directory (on one volume).
-
-``sleep <number>...``
- Sleep for given number of seconds.
-
-``tar [cxt][vf][zjJ] file.tar [<options>...] [--] [<file>...]``
- Create or extract a tar or zip archive. Options are:
-
- ``--``
- Stop interpreting options and treat all remaining arguments
- as file names even if they start in ``-``.
- ``--files-from=<file>``
- Read file names from the given file, one per line.
- Blank lines are ignored. Lines may not start in ``-``
- except for ``--add-file=<name>`` to add files whose
- names start in ``-``.
- ``--mtime=<date>``
- Specify modification time recorded in tarball entries.
- ``--format=<format>``
- Specify the format of the archive to be created.
- Supported formats are: ``7zip``, ``gnutar``, ``pax``,
- ``paxr`` (restricted pax, default), and ``zip``.
-
-``time <command> [<args>...]``
- Run command and return elapsed time.
-
-``touch <file>``
- Touch a file.
-
-``touch_nocreate <file>``
- Touch a file if it exists but do not create it. If a file does
- not exist it will be silently ignored.
-
-UNIX-specific Command-Line Tools
---------------------------------
-
-The following ``cmake -E`` commands are available only on UNIX:
-
-``create_symlink <old> <new>``
- Create a symbolic link ``<new>`` naming ``<old>``.
-
-Windows-specific Command-Line Tools
------------------------------------
-
-The following ``cmake -E`` commands are available only on Windows:
-
-``delete_regv <key>``
- Delete Windows registry value.
-
-``env_vs8_wince <sdkname>``
- Displays a batch file which sets the environment for the provided
- Windows CE SDK installed in VS2005.
-
-``env_vs9_wince <sdkname>``
- Displays a batch file which sets the environment for the provided
- Windows CE SDK installed in VS2008.
-
-``write_regv <key> <value>``
- Write Windows registry value.
-
-Find-Package Tool Mode
-======================
-
-CMake provides a helper for Makefile-based projects with the signature::
-
- cmake --find-package <options>...
-
-This runs in a pkg-config like mode.
-
-Search a package using :command:`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``).
-
-.. note::
- This mode is not well-supported due to some technical limitations.
- It is kept for compatibility but should not be used in new projects.
