[vtkusers] More QT and VTK Problems

[Michael Rice]

Yes, this is the proper way to do it. Changes made to the qmake.conf  
file are automatically picked up by qmake.

I haven't used mingw, so I'm not sure how the LIBS setting should be.  
The example I gave is for using the MS linker. For more *nix type  
environments, the LIBS line should look more like:

LIBS += -L$$VTKLIBDIR \
         -lQVTK -lvtkHybrid -lvtkIO ...
