[vtkusers] Linker errors after upgrading to vtk 5.6.1

[Joseph D. Wieber Jr.]

The only way to get my app to compile is to add all the libs to the LIBS 
variable thus:

LIBS += -lCosmo \
         -lMapReduceMPI \
         -lmpistubs \
         -lQVTK \
         -lVPIC \
         -lvtkalglib \
         -lvtkCharts \
         -lvtkCommon \
         -lvtkDICOMParser \
         -lvtkexoIIc \
         -lvtkexpat \
         -lvtkFiltering \
         -lvtkfreetype \
         -lvtkftgl \
         -lvtkGenericFiltering \
         -lvtkGeovis \
         -lvtkGraphics \
         -lvtkHybrid \
         -lvtkImaging \
         -lvtkInfovis \
         -lvtkIO \
         -lvtkjpeg \
         -lvtklibxml2 \
         -lvtkmetaio \
         -lvtkNetCDF \
         -lvtkNetCDF_cxx \
         -lvtkParallel \
         -lvtkpng \
         -lvtkproj4 \
         -lvtkQtChart \
         -lvtkRendering \
         -lvtksqlite \
         -lvtksys \
         -lvtktiff \
         -lvtkverdict \
         -lvtkViews \
         -lvtkVolumeRendering \
         -lvtkWidgets \
         -lvtkzlib

This seems out of the ordinary since I only use a handful of vtk classes 
in my app.
