[vtkusers] find_package( ITK ) overrides ${VTK_LIBRARIES} from find_package( VTK )

[David Gobbi]

Hi Pablo,

It's best to only link to the VTK libraries that you need, rather than
trying to
link to them all via ${VTK_LIBRARIES}.

The reason for the short list is probably that when ITK calls
find_package(),
it only requests the small set of VTK components that ITK uses:
