CMAKE_VS_PLATFORM_TOOLSET

Visual Studio Platform Toolset name.

VS 10 and above use MSBuild under the hood and support multiple compiler toolchains. CMake may specify a toolset explicitly, such as v110 for VS 11 or Windows7.1SDK for 64-bit support in VS 10 Express. CMake provides the name of the chosen toolset in this variable.

See the :variable:CMAKE_GENERATOR_TOOLSET variable for details.
