You could try to compile a simple C++ program first without CMake. E.g. store a simple main.cpp somewhere in your user directory C:Users<yourname>Temp directory with following content:

int main() 
{
   return 0;
}

Now open CMD window in your C:Users<yourname>Temp directory and run:

C:MinGWingcc.exe main.cpp -o testprog

If an error popup appears that is saying something about a missing .dll, run following command in your CMD window and try to compile again:

set PATH=%PATH%;C:MinGWin

If you had to run the last command, add the C:MinGWin path permanently. After all it should be possible to run CMake with MinGW as compiler.
