I have a cmake project for building a shared C++ library on Windows. There I would like to append the PlatformToolset information to the libraries file name.

I know the cMake variable CMAKE_GENERATOR_TOOLSET where the Platform Toolset is defined when it is specified with the configuration command. e.g.: cmake -G "Visual Studio 16 2019" -A x64 -T v141 .

Unfortunately the CMAKE_GENERATOR_TOOLSET variable is not defined when the default toolset (-T option not specified) is used.

Is there any way to get the default toolset information in my CMakeLists.txt file? Or does I have to manually define the Toolset information based on the MSVC_VERSION?
