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

[Amine Chadly]

Hi,
Isn't it a problem with the where it's looking for the compiler ?
is c:/MinGW/bin/gcc.exe an equivalent of /mingw/bin/gcc.exe ?

You can try to play around with a simple Makefile and setting the CC environment variable to see what are the correct values.

Hope it helps...
