| 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 |
| * The :generator:`Green Hills MULTI` generator |
| |
| 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=<arch>`` |
| Specify the host tools architecture as ``x64`` or ``x86``. |
| Supported by VS 2013 and above. |
| See the :variable:`CMAKE_VS_PLATFORM_TOOLSET_HOST_ARCHITECTURE` |
| variable. |
| |
| ``version=<version>`` |
| Specify the toolset version to use. Supported by VS 2017 |
| and above with the specified toolset installed. |
| See the :variable:`CMAKE_VS_PLATFORM_TOOLSET_VERSION` variable. |
