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

[Cory Quammen]

Pablo,

I was just looking into this myself after encountering the same behavior.

If you want to include the VTK libraries needed for ITK and specify an
additional set of VTK modules in your project, I suggest the
following:

find_package(ITK REQUIRED)
include(${ITK_USE_FILE})

set(VTK_MODULES_REQUESTED ${VTK_MODULES_REQUESTED} [additional VTK modules])
find_package(VTK REQUIRED)
include(${VTK_USE_FILE})

This should work. VTK_LIBRARIES should be set to only the VTK
libraries needed for the modules requested by ITK and by you, plus
their dependencies. Let us know if it doesn't.

Thanks,
Cory
