[CMake] Qt4

[John Biddiscombe]

Filipe

Did you solve Qt4 problems. I've just finished installing Qt4, run the 
demos, done my first hello world app and have discovered that cmake is 
generating the wrong stuff for Qt4. I'll start experimenting, but if 
you've already found a working solution, please tell.

thanks

JB
