Not only that, actually the whole logic how include dirs and libs are 
searched.

I'm doing the merging always both ways in general, except the stuff where I'm 
not sure it makes sense for the broader public.

That's a more long term goal, since this implies that we will require that of 
version of cmake which comes with the merged version, i.e. at most 2.8.1.
Upgrading the required cmake version just for the FindQt4.cmake would not make 
sense I'd say, there must be more reasons to justify an upgrade.
