Can you explain why?
Is it because you have dependent modules that you don't use directly, that 
need to be turned on for linking?

In the past, I've thought of modifying UseQt4.cmake to partially turn on 
dependent modules automatically (for linking), which would allow not having 
as many include directories.

This would allow for behavior closer to what qmake does.
