You can try, but my guess is that you should not expect a warm welcome for patches doing so. CMake may be slower, but it has shown to be able to deal with a whole lot of weird things on all platforms. The main devs and Dick (I am not) have spent so much time on this, that I doubt they´ll be very receptive. Also, kicad used Wx, why use a QT build-system?

I am not trying to start a flamefest, but perhaps it convinces you to spend that time on other KiCad improvements.

Kind regards,
Martijn
