Yes, sure, but I'm away from this noon until Sunday evening.
Is this needed already now for 4.7 ?

I was hoping to have some more weeks to give it more testing and finish it.
("it" being the "Superbuild" CMakeLists.txt, which provide builds in old-style 
KDE modules or in the future maybe even an all-in-one build using CMakes 
ExternalProject feature).
In git there is a repository superbuild now, but it's not yet done.

What still needs to be done:
- add special handling DESTDIR
- add handling for tags
- maybe some work on the implementation of ExternalProject in cmake

For which modules is this right now ?
kdesupport, kdegraphics, more ?
