Problem: CMake evaluation fails with Mingw-w64

Browse Source 
Solution: we can use 'CMAKE_SYSTEM_VERSION' instead of
'${CMAKE_SYSTEM_VERSION}' for the 'if' clauses.

CMake fails to evaluate condition when CMAKE_SYSTEM_VERSION is
empty, which can happen with a default installation of Mingw-w64
in Linux.
