In theory it should work, but the mingw version they ship doesn't work.

I've upgraded to a version of make which does (one needs to pass
SHELL=cmd.exe as an additional parameter), but when you haven't changed
anything it still takes some time. This is where ninja comes into place.

CMake sets the right flags for qcc and qcc creates the dependency files.
