MSVC_TOOLSET_VERSION

The toolset version of Microsoft Visual C/C++ being used if any. If MSVC-like is being used, this variable is set based on the version of the compiler as given by the MSVC_VERSION variable.

Known toolset version numbers are:

80        = VS 2005 (8.0)
90        = VS 2008 (9.0)
100       = VS 2010 (10.0)
110       = VS 2012 (11.0)
120       = VS 2013 (12.0)
140       = VS 2015 (14.0)
141       = VS 2017 (15.0)

Compiler versions newer than those known to CMake will be reported as the latest known toolset version.
