I tried to test this but it did not apply in master. Could you rebase it?
On my 64+64 core system that is shared, it reduced a webkit compile
from ~ 17 minutes to ~12 minutes for just the compile stage. YMMV.

I'm going to try to build world (oe-core + meta-oe + ...).
Octavio, it's a two line change! :)
This applied to master for me:

cmake: use Ninja backend instead of Make
The Ninja backend is faster than Make for large projects
(it takes three minutes off webkitgtk:do_compile for example)
so use it by default.
