This is needed to compile both in a single call to make. Also it will
help removing some of the mistakes in the current android version:
it always created the mainwindow, even without using it for anything,
so tons of memory will be freed now for the android version, making it
snappier and smoother.
This is a necessary move so we don't need to #ifdef all over the place
for the two different versions, and imo the changes needed to keep both
versions will not be that huge if we keep things in subsurface-core
sane.
