I'm not opposed to it, but I have the feeling that it belongs to a different
layer, so this means creating a build directory to call flatpak to call cmake.
Also the arguments one passes to cmake won't have any effect on the flatpak.
What's the reason you want to work on it? maybe we should work in simplifying
the flatpak-builder call?
