- CMAKE_GENERATOR_TOOLSET
- -----------------------
- Native build system toolset specification provided by user.
- Some CMake generators support a toolset specification to tell the
- native build system how to choose a compiler. If the user specifies
- a toolset (e.g. via the :manual:`cmake(1)` ``-T`` option) the value
- will be available in this variable.
- The value of this variable should never be modified by project code.
- A toolchain file specified by the :variable:`CMAKE_TOOLCHAIN_FILE`
- variable may initialize ``CMAKE_GENERATOR_TOOLSET``. Once a given
- build tree has been initialized with a particular value for this
- variable, changing the value has undefined behavior.
- Toolset specification is supported only on specific generators:
- * :ref:`Visual Studio Generators` for VS 2010 and above
- * The :generator:`Xcode` generator for Xcode 3.0 and above
- See native build system documentation for allowed toolset names.
- Visual Studio Toolset Selection
- ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
- The :ref:`Visual Studio Generators` support toolset specification
- using one of these forms:
- * ``toolset``
- * ``toolset[,key=value]*``
- * ``key=value[,key=value]*``
- The ``toolset`` specifies the toolset name. The selected toolset name
- is provided in the :variable:`CMAKE_VS_PLATFORM_TOOLSET` variable.
- The ``key=value`` pairs form a comma-separated list of options to
- specify generator-specific details of the toolset selection.
- Supported pairs are:
- ``cuda=<version>``
- Specify the CUDA toolkit version to use. Supported by VS 2010
- and above with the CUDA toolkit VS integration installed.
- See the :variable:`CMAKE_VS_PLATFORM_TOOLSET_CUDA` variable.
- ``host=x64``
- Request use of the native ``x64`` toolchain on ``x64`` hosts.
- Supported by VS 2013 and above.
- See the :variable:`CMAKE_VS_PLATFORM_TOOLSET_HOST_ARCHITECTURE`
- variable.
