[Cmake] does the GENERATED property work ?

[William A. Hoffman]

If you could provide a complete example that shows the problem, but
used something more like the copy used in the FAQ entry I sent, I could
take a look.   (I don't have qt on my system so I can not test your code.)
Also, your cmakelist file is not complete, I would need a complete test that
showed the problem.
