``-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 :command:`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.
``-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
Generators section.
``-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.
``-Wdev``
Enable developer warnings.
Enable warnings that are meant for the author of the CMakeLists.txt
files.
