This is a problem that has been cropping up in our projects that use ITK, VTK and SlicerExecutionModel.
You won’t see it UNLESS you turn on the ITKVTK/ITKVtkGlue modules. The problem is this: if you find packages in this order: find_package(VTK REQUIRED) find_package(ITK REQUIRED) You can’t real compile anything that needs VTK, because down in the ITK deployment stuff, it calls find_package(VTK) like this: find_package(VTK COMPONENTS vtkCommonCore vtkRenderingCore vtkRenderingOpenGL vtkRenderingFreeType vtkInteractionStyle vtkIOImage vtkImagingSources REQUIRED) Which blows away the larger list of include directories and libraries that the first find_package(VTK REQUIRED) built. Even better — or worse — Modules/Segmentation/LevelSetsv4Visualization/CMakeLists.txt also include find_package(VTK) — so ITK tries to import VTK twice, with different module lists. It doesn’t even help to reverse the order: find_package(ITK REQUIRED) find_package(VTK REQUIRED) because apparently there’s some hangover from the find_package(VTK) inside the ITK CMake deployment files. The only thing that works is to use COMPONENTS, i.e. find_package(ITK REQUIRED) find_package(VTK COMPONENTS vtkCommonCore vtkRenderingAnnotation … REQUIRED) Which seems to trigger a proper re-scan and build of the library/include lists. It gets even worse if you use find_package(SlicerExecutionModel) after find_package(ITK), for the same reason — SlicerExecutionModel depends on ITK, so it clobbers the include/library lists from the first find_package(ITK). ________________________________ Notice: This UI Health Care e-mail (including attachments) is covered by the Electronic Communications Privacy Act, 18 U.S.C. 2510-2521, is confidential and may be legally privileged.
