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

[Pablo Hernández]

Thanks a lot, I have tested Bill suggestion and it worked:

> before
> find_package(VTK REQUIRED)

And thanks for pointing out that linking all the libraries is not good, but I've some problems knowing what module corresponds to my #include<vtk**> header.  Is there any wiki page to discover that or any map linking module-library?

Thanks all for the solutions,
Pablo
