Hi,

thanks for the useful hints, cmake finds the package now. But 
unfurtunally, it does not link the library and therefore i get a lot of 
unresolved dependency from gdcm. i replaced my stuff with

FIND_PACKAGE(GDCM REQUIRED)
INCLUDE(${GDCM_USE_FILE})

and tested the typical variables

MESSAGE(STATUS "Cmake GDCM: using GDCM includes at: ${GDCM_INCLUDE_DIR}")
MESSAGE(STATUS "Cmake GDCM: using GDCM libraries: ${GDCM_LIBRARIES}")
MESSAGE(STATUS "Cmake GDCM: using GDCM libraries: ${GDCM_LIBRARY}")

but the are all empty? How can i find out, what is defined by GDCM?

Bye.
