It applies a two step process: # # * Step 1: Attempt to find DCMTK version providing a *DCMTKConfig.cmake* file. # * Step 2: If step 1 failed, rely on *FindDCMTK.cmake* to set `DCMTK_*` variables details below. # # # `Recent DCMTK # `_ # provides a *DCMTKConfig.cmake* :manual:`package configuration file # `. To exclusively use the package configuration file # (recommended when possible), pass the `NO_MODULE` option to # :command:`find_package`. For example, `find_package(DCMTK NO_MODULE)`. # This requires official DCMTK snapshot *3.6.1_20140617* or newer. # # # Until all clients update to the more recent DCMTK, build systems will need # to support different versions of DCMTK. # # On any given system, the following combinations of DCMTK versions could be # considered: # # +--------+---------------------+-----------------------+-------------------+ # | | SYSTEM DCMTK | LOCAL DCMTK | Supported ? | # +--------+---------------------+-----------------------+-------------------+ # | Case A | NA | [ ] DCMTKConfig | YES | # +--------+---------------------+-----------------------+-------------------+ # | Case B | NA | [X] DCMTKConfig | YES | # +--------+---------------------+-----------------------+-------------------+ # | Case C | [ ] DCMTKConfig | NA | YES | # +--------+---------------------+-----------------------+-------------------+ # | Case D | [X] DCMTKConfig | NA | YES | # +--------+---------------------+-----------------------+-------------------+ # | Case E | [ ] DCMTKConfig | [ ] DCMTKConfig | YES (*) | # +--------+---------------------+-----------------------+-------------------+ # | Case F | [X] DCMTKConfig | [ ] DCMTKConfig | NO | # +--------+---------------------+-----------------------+-------------------+ # | Case G | [ ] DCMTKConfig | [X] DCMTKConfig | YES | # +--------+---------------------+-----------------------+-------------------+ # | Case H | [X] DCMTKConfig | [X] DCMTKConfig | YES | # +--------+---------------------+-----------------------+-------------------+ # # (*) See Troubleshooting section. # # Legend: # # NA ...............: Means that no System or Local DCMTK is available # # [ ] DCMTKConfig ..: Means that the version of DCMTK does NOT export a DCMTKConfig.cmake file. # # [X] DCMTKConfig ..: Means that the version of DCMTK exports a DCMTKConfig.cmake file. # # # Troubleshooting # ^^^^^^^^^^^^^^^ # # What to do if my project finds a different version of DCMTK? # # Remove DCMTK entry from the CMake cache per :command:`find_package` # documentation. # # Written for VXL by Amitha Perera. # Upgraded for GDCM by Mathieu Malaterre. # Modified for EasyViz by Thomas Sondergaard. # set(_dcmtk_dir_description "The directory of DCMTK build or install tree.") # Ensure that DCMTK_DIR is set to a reasonable default value # so that DCMTK libraries can be found on a standard Unix distribution. # It also overwrite the value of DCMTK_DIR after this one has been # set by a successful discovery of DCMTK by the unpatched FindDCMTK.cmake module # distributed with CMake (as of 0167cea) if(NOT DCMTK_DIR OR DCMTK_DIR STREQUAL "/usr/include/dcmtk") set(DCMTK_DIR "/usr" CACHE PATH ${_dcmtk_dir_description} FORCE) endif() set(_SAVED_DCMTK_DIR ${DCMTK_DIR}) # # Step1: Attempt to find a version of DCMTK providing a DCMTKConfig.cmake file. # if(NOT DCMTK_FIND_QUIETLY) message(STATUS "Trying to find DCMTK expecting DCMTKConfig.cmake") endif() find_package(DCMTK QUIET NO_MODULE) if(DCMTK_FOUND AND NOT "x" STREQUAL "x${DCMTK_LIBRARIES}" AND NOT "x" STREQUAL "x${DCMTK_INCLUDE_DIRS}") if(NOT DCMTK_FIND_QUIETLY) message(STATUS "Trying to find DCMTK expecting DCMTKConfig.cmake -
