Hello Eduardo,
without exactly knowing what you expect your DICOM application to do ...
Did you compile the ITK with ITK_USE_SYSTEM_GDCM (CMake-option of ITK)? If you did not, you should. This causes the ITK to take the system-installed GDCM (usually 2.++) instead of the one shipped with the ITK. If you did that you do no longer have to enter the GDCM-specific CMakeLists-entries (FIND_PACKAGE(GDCM) and so on), it should normally be sufficient to do the FIND_PACKAGE(ITK) stuff.
I had similar problems with a mixed-up ITK/VTK/GDCM2.0 application at the very beginning (the error messages were partially funny and not really trackable).
HTH,
lars
