[Paraview] Plugin Verification Data Mismatch

[Christian Werner]

Hmm, I don't see how I can provide this information to my compiler since 
the usual way outside ParaView is to have a CMakeList which contains 
something like this

TARGET_LINK_LIBRARIES( vtkITKImageBox
   ITKCommon ITKIO
   vtkCommon vtkIO
)

But when I do this in my ParaView-Plugin CMakeList, I get an error message:

CMake Error at CMakeLists.txt:16 (TARGET_LINK_LIBRARIES):
Cannot specify link libraries for target "vtkITKImageBox" which is not
built by this project.

That's odd because the CMakeList for the VTK-only environment contains 
exactly these lines and everything works. Obviously this has to be 
handled differently for ParaView, but how? It compiled and linked 
without any of this target_link_library stuff in the first place, which 
is strange, because I do need some libraries... ??

So I thought maybe these libraries are only important at runtime, but 
adding the path to the ITK libraries to the LD_LIBRARY_PATH did not help 
either.
