I was upgrading my G++ compiler with MinGW to version 8.2.0. Now Cmake is not working anymore.
Working on a 64bit Win10.
It's telling me that "gcc.exe is not able to compile a simple test program". While both compilers, gcc and g++ are working for me on the console.
I already tried reinstalling the compiler several times without any result.
