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.

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>``
|
|
Build a CMake-generated project binary tree.
|
|
|
|
This abstracts a native build tool's command-line interface with the
|
|
following options:
|
|
|
|
::
|
|
|
|
<dir> = Project binary directory to be built.
|
|
--target <tgt> = Build <tgt> instead of default targets.
|
|
May only be specified once.
|
|
--config <cfg> = For multi-configuration tools, choose <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.
|
|
|
|
``-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``
|
|
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 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.

Command-Line Tool Mode

cmake -E <command> [<options>...]
|
|
|
|
Run ``cmake -E`` or ``cmake -E help`` for a summary of commands.

|
|
Change the current working directory and run a command.
|
|
|
|
``compare_files <file1> <file2>``
|
|

|
|
then returns 0, if not itreturns 1.
|
|
|
|
``copy <file>... <destination>``
|
|
Copy files to ``<destination>`` (either file or directory).

|
|
directory and it must exist.
|
|
|
|
``copy_directory <dir>... <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.
|
