[vtkusers] Linker errors after upgrading to vtk 5.6.1

[Joseph D. Wieber Jr.]

Hi all,

I upgraded to vtk5.6.1 (using cmake) and tried to rebuild an existing Qt 
based project, and now I'm getting 717 link errors.  I verified my paths 
in the qmake file, and environment, are correct.  In vtk5.4 I only 
needed to link against -lvtkCommon -lvtkRendering -lvtkVolumeRendering 
-lQVTK.  With 5.6.1 I get a slew of warnings of the form:

/usr/bin/ld: warning: libvtksys.so.5.6, needed by 
/usr/lib/vtk-5.6/libvtkCommon.so, not found (try using -rpath or 
-rpath-link)

followed by 717 undefined reference errors.  So, I add the unfound 
library named in the to the list, but then the link error count goes 
up.  It seems strange that I should be getting all these linker errors.  
Any idea what could be wrong?  I'm using qmake from within the Qt 
Creator IDE.  Below is my .pro file.  In the build settings I have the 
variable LIBRARY_PATH=:/usr/lib/nvidia-current:/usr/lib/vtk-5.6.  I also 
tried adding -L/usr/lib/vtk-5.6 to the LIBS variable, but that didn't 
help either.  Could it be possible that I need to have all 36 libraries 
listed to link against?  Note, in the warning above ld knows the correct 
path to the vtk shared libs.

.pro file:
