I did not realize that cmake calls mingw32-make.exe, since the user has to call it explicitly after running cmake.  But I see now.  Cmake tries compiling as a part of finding the compilation tools.

Your suggestion worked, for both W32 and W64.  I used -G "MinGW Makefiles" for both cases.

This also works with CMake 2.8 stable/release version.  So I still cannot figure what's new in RC2 with respect to MinGW-W64.  Since it works, there is no issue really.

Just like CMake is able to distinguish different versions of Visual Studio, would it distinguish MinGW-32 with MinGW-64 also (which means either both would be in path simultaneously, or neither would be, and cmake picks the right one based on the generator specifed)?  Let me know if so, and I'll be happy to test this.

I have already reported missing mingw32-make.exe to MinGW-W64.
