Hi,
I know I can check MSVC to determine if the Visual Studio generator is
used. But how do I find out which version is been used?
MSVC indicates that the Visual C++ compiler (or something compatible) is
being used; which does not necessarily mean a Visual Studio generator.
If you do need to make that distinction you can check MSVC_IDE [1] instead.
The reason I want to find the the version of VS being used, is because
I need to link to the Boost libraries. Boost create its libraries with
suffixes like "-vs120-mt", etc. and "vs120" indicates Visual Studio 2013.
Why aren't you using the Boost find module[2] included with CMake? It
already accounts for Boost's library name mangling.
The module uses e.g. the MSVC12 [3] variable to detect "vc120".
But I am guessing CMAKE_<LANG>_COMPILER_VERSION [4] might work for this
use case nowadays as well.
