[vtkusers] How to specify the path to VTK in CMake?

[André Prins]

Dear Michael,

I am sorry, I was not of much help to you. My CMakeLists file does
nothing more than

    # Finding Vtk-5, based on a known VTKDIR environment-variable
    message( STATUS "Find Vtk-5 using $ENV{VTKDIR}" )
    find_package( VTK REQUIRED HINTS $ENV{VTKDIR} )
    include( ${VTK_USE_FILE} )

and then add the correct target_link_libraries to my target, just like
Cyrille demonstrated in an example. Did you put a
target_link_libraries line in you CMakeLists.txt In my case:

    add_executable( test_Visualizations ${TEST_H_HEADERS} ${TEST_CPP_SOURCES} )
    target_link_libraries( test_Visualizations vtkRendering vtkWidgets
vtkHybrid )

Other than that my CMakeLists file does not do anything but collect
source-files... However, I have had issues with Visual Studio with the
link-directories and include-directories not being set by cmake. Did
you try to clear the CMakeCache.txt file? Or tried a clean build?

Regards,
Andre
