[CMake] Testing Qt 5 RC 1 CMake files

[lonka]

Hi Stephen,

I have tried to build vtk from master (applying your patch) with qt5 but I
can not succeed.
What I get is:

I am not sure if it has anything to do with the fact that the type argument
to the Q_DECLARE_METATYPE macro must be fully defined, not forward declared
as described here:
porting-from-qt-4-to-qt-5/ <http://www.kdab.com/porting-from-qt-4-to-qt-5/>  

In GUISupport/Qt/vtkQtDebugLeaksView.cxx:208 
Q_DECLARE_METATYPE(vtkObjectBase*);

I am using Ubunty 12.10. x86_64. 
gcc version 4.6.3

Do you have any idea if there is anything I can do to get it compiled?
