[CMake] [3.1.0] [PATCH] CMP0054 in CMakeDetermineCXXCompiler.cmake

[Paul Anton Letnes]

Just wanted to say that I've seen the same issue on my system:
Visual studio 2013, Win 7 64
Cmake 3.1.0-rc2 
Intel fortran 2015 (used for the fortran bits of a mixed c/c++/fortran solution)

Cheers 
Paul

PS: I envy your email address.
