[Insight-developers] [Insight-users] CMake config problem: ITK + GDCM 2 + VTK

Sat Jul 17 17:17:50 EDT 2010

Hi Stephen,

  Here is how the cmake/gdcm config/use file is setup:

$ cat /usr/lib/gdcm-2.0/UseGDCM.cmake
...
  # Use VTK.
  IF(GDCM_USE_VTK)
    SET(VTK_DIR ${GDCM_VTK_DIR})
    FIND_PACKAGE(VTK)
    IF(VTK_FOUND)
      INCLUDE(${VTK_USE_FILE})
    ELSE(VTK_FOUND)
      MESSAGE("VTK not found in GDCM_VTK_DIR=\"${GDCM_VTK_DIR}\".")
    ENDIF(VTK_FOUND)
  ENDIF(GDCM_USE_VTK)
...

  This setting is required since vtkgdcm class derives from vtk
classes. This means compilation would fails if the VTK header would
not be found. Therefore I believe this is a requirement for vtkgdcm
module to pull in vtk cmake setting.

  Could you please recommend another way for doing this ?

Thanks for your comments !
-Mathieu
