`cmake --help-module` parses system installed Find*.cmake file,
however it does not parse *Config.cmake file. You have to look into
GDCMConfig.cmake and such to understand.
Anyway, there is no generic "GDCM_LIBRARIES", you have to specify
explicitely the name of the desired lib:
add_executable(dummy dummy.cxx)
target_link_libraries(dummy gdcmMSFF)

Hello,
i found GDCMconfig.cmake as you mentioned and the definitions there in
are GDCM_INCLUDE_DIRS and GDCM_LIBRARY_DIRS. But as in the former post i
specified the needed libraries manually. Thank you all for your help.
FIND_PACKAGE(GDCM REQUIRED)
INCLUDE(${GDCM_USE_FILE})
SET(GDCM_LIBRARIES gdcmCommon gdcmDICT gdcmDSED gdcmIOD
gdcmjpeg8 gdcmjpeg12 gdcmjpeg16 gdcmMSFF
CACHE STRING "GDCM libraries")
MESSAGE(STATUS "Cmake GDCM: using includes at: ${GDCM_INCLUDE_DIRS}")
MESSAGE(STATUS "Cmake GDCM: using libraries at: ${GDCM_LIBRARY_DIRS}")
MESSAGE(STATUS "Cmake GDCM: using libraries: ${GDCM_LIBRARYRIES}")
TARGET_LINK_LIBRARIES(fileInfo ${GDCM_LIBRARIES})
But it is still unclear to me how to provide different link_directories
for Debug and Release used by MSVC 9.0 on Windows for external libraries
not using cmake . If i have release and debug libraries with different
namens (i.e. test1.lib and test1d.lib) i can use something like
TARGET_LINK_LIBRARIES( Project1 debug test1d.lib optimized test1.lib)
But what if i have i.e. Debug/test1.lib and Release/test1.lib? How do i
define configuration-type depended LINK_DIRECTORIES?
Best reguards,
Michael
