[vtkusers] More QT and VTK Problems

[Michael Rice]

You need to add the paths to the VTK includes and libraries paths to  
the .pro file. You also need to add the VTK libraries to link to.

For example (adjust as appropriate):

TEMPLATE = app
VTKDIR = C:/VTK
VTKLIBDIR = $$VTKDIR/bin
DEPENDPATH += .
INCLUDEPATH += . \
                $$VTKDIR/Common \
                $$VTKDIR/Filtering \
                $$VTKDIR/GUISupport/Qt \
                $$VTKDIR/GenericFiltering \
                $$VTKDIR/Graphics \
                $$VTKDIR/Hybrid \
                $$VTKDIR/IO \
                $$VTKDIR/Imaging \
                $$VTKDIR/Rendering \
                $$VTKDIR/Utilities \
                $$VTKDIR/Widgets
LIBS += $$VTKLIBDIR/QVTK.lib \
         $$VTKLIBDIR/vtkHybrid.lib \
         $$VTKLIBDIR/vtkIO.lib \
         $$VTKLIBDIR/vtkImaging.lib \
         $$VTKLIBDIR/vtkRendering.lib \
         $$VTKLIBDIR/vtkWidgets.lib \
         $$VTKLIBDIR/vtkGraphics.lib \
         $$VTKLIBDIR/vtkFiltering.lib \
         $$VTKLIBDIR/vtkGenericFiltering.lib \
         $$VTKLIBDIR/vtkCommon.lib \
         $$VTKLIBDIR/vtkexoIIc.lib \
         $$VTKLIBDIR/vtkexpat.lib \
         $$VTKLIBDIR/vtkftgl.lib \
         $$VTKLIBDIR/vtkjpeg.lib \
         $$VTKLIBDIR/vtkpng.lib \
         $$VTKLIBDIR/vtktiff.lib \
         $$VTKLIBDIR/vtksys.lib \
         $$VTKLIBDIR/vtkzlib.lib \
