It checks VS_PLATFORM_TOOLSET_VERSION but never uses the value, it uses VS_TOOLSET_VERSION instead. This change switches to use VS_PLATFORM_TOOLSET_VERSION (which aligns with CMake's CMAKE_VS_PLATFORM_TOOLSET_VERSION), and then sets CMAKE_VS_PLATFORM_TOOLSET_VERSION with the resolved value.
At the minute VS_PLATFORM_TOOLSET_VERSION has to be an exact match - #79 tracks adding support for approximate matches, like vcvarsall.bat does.
