cmake - CMake Command-Line Reference
SYNOPSIS
cmake [<options>] (<path-to-source> | <path-to-existing-build>)
cmake [(-D <var>=<value>)...] -P <cmake-script-file>
cmake --build <dir> [<options>] [-- <build-tool-options>...]
cmake -E <command> [<options>...]
cmake --find-package <options>...
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
-C <initial-cache>
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 <var>:<type>=<value>, -D <var>=<value>
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.
If the :<type> portion is given it must be one of the types specified by the set()
command documentation for its CACHE signature. If the :<type> portion is omitted
the entry will be created with no type if it does not exist with a type already.
If a command in the project sets the type to PATH or FILEPATH then the <value> will
be converted to an absolute path.
This option may also be given as a single argument: -D<var>:<type>=<value> or
-D<var>=<value>.
-U <globbing_expr>
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 <generator-name>
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 cmake-generators(7) manual.
-T <toolset-name>
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.
-A <platform-name>
Specify platform name if supported by generator.
Some CMake generators support a platform name to be given to the native build
system to choose a compiler or SDK. This is supported only on specific generators:
Visual Studio >= 8
See native build system documentation for allowed platform names.
-Wno-dev
Suppress developer warnings.
Suppress warnings that are meant for the author of the CMakeLists.txt files. By
default this will also turn off deprecation warnings.
-Wdev Enable developer warnings.
Enable warnings that are meant for the author of the CMakeLists.txt files. By
default this will also turn on deprecation warnings.
-Werror=dev
Make developer warnings errors.
Make warnings that are meant for the author of the CMakeLists.txt files errors. By
default this will also turn on deprecated warnings as errors.
-Wno-error=dev
Make developer warnings not errors.
Make warnings that are meant for the author of the CMakeLists.txt files not errors.
By default this will also turn off deprecated warnings as errors.
-Wdeprecated
Enable deprecated functionality warnings.
Enable warnings for usage of deprecated functionality, that are meant for the
author of the CMakeLists.txt files.
-Wno-deprecated
Suppress deprecated functionality warnings.
Suppress warnings for usage of deprecated functionality, that are meant for the
author of the CMakeLists.txt files.
-Werror=deprecated
Make deprecated macro and function warnings errors.
Make warnings for usage of deprecated macros and functions, that are meant for the
author of the CMakeLists.txt files, errors.
-Wno-error=deprecated
Make deprecated macro and function warnings not errors.
Make warnings for usage of deprecated macros and functions, that are meant for the
author of the CMakeLists.txt files, not errors.
-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.
--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.
