I thought about that at first, but it's rather weird, as graphics SDK doesn't 
have build dependency on those packages, mostly because it's already 
pre-built...

I was going to experiment with it a bit to see if it would be possible to use 
this graphics SDK w/o wayland libs, hence I just wanted to unblock qtbase for 
now, as it's configure test fails.
