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

[Pablo Hernández]

I have compiled ITK with the use_vtk option. And now ITK overrides the VTK_LIBRARIES, with a really small list of libraries.

find_package(ITK 4.5 REQUIRED)                                           
message (status "** ITK FOUND: USE_FILES ${ITK_USE_FILE}")               
message (status "** VTK FOUND: USE_FILES ${VTK_USE_FILE}")               
message (status "** VTK FOUND: VTK_LIBRARIES ${VTK_LIBRARIES}") 

find_package(VTK 6.2 REQUIRED)
message (status "** VTK FOUND: USE_FILES ${VTK_USE_FILE}")
message (status "** VTK FOUND: VTK_LIBRARIES ${VTK_LIBRARIES}")

Output:
status** ITK FOUND: USE_FILES /home/phc/Software/ITK/install-debug-nocuda-v461/lib/cmake/ITK-4.7/UseITK.cmake
status** VTK FOUND: USE_FILES /home/phc/Software/VTK/installation/qt5-git/lib/cmake/vtk-6.2/UseVTK.cmake

--Same output TWICE ...--

If I find VTK first and then ITK I got the same results.

But if I don't find ITK, ie. with VTK alone I get the triple amount of libraries, and I need those libraries to compile my code.
Is this a bug in ITK (or cmake, or VTK) or am I doing something wrong in my CMakeLists.txt?
