[CMake] how to build cmake with mingw and msys?

[John Poole]

I will not be at my windows machine for several day where I've been trying
cmake in MinGW; but I think I had the same problem you have run into.  I
think the path construction is very sensitive, have your tried
"/c/MinGW/bin/gcc.exe" or "/c:/MinGW/bin/gcc.exe"
