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

[Pablo Hernández]

I  have a running/compiling CMakeLists.txt when using VTK only, this is the related VTK part:
find_package(VTK 6.2 REQUIRED)
 message (status "** VTK FOUND: USE_FILES ${VTK_USE_FILE}")
message (status "** VTK FOUND: VTK_LIBRARIES ${VTK_LIBRARIES}")

include(${VTK_USE_FILE})
include_directories( ${VTK_INCLUDE_DIRS}) 
include_directories(${CMAKE_CURRENT_SOURCE_DIR})

add_executable(VTKNodesEdgesEXE main.cpp ${source_files} ${QT_UI_HEADERS} ${QT_RESOURCES})
target_link_libraries(VTKNodesEdgesEXE ${VTK_LIBRARIES})
target_link_libraries(VTKNodesEdgesEXE Qt5::Widgets Qt5::PrintSupport)


The problem is that if I add find_package(ITK) anywhere, ${VTK_LIBRARIES} gets overrides by a tiny list selected by ITK.
