[vtkusers] Patch for vtk 5.0.1 (and probably later releases too)

[David Cole]

You can try setting the advanced CMake configuration variable
"VTK_USE_SYSTEM_TIFF" to ON. That should avoid building the VTK version of
the TIFF library altogether and let you use your system TIFF library.
I have not tried this myself, but that's how it should work in theory.

HTH,
David
