I am working on updating the FindDCMTK.cmake module. It includes a lot of commands like the following: FIND_LIBRARY( DCMTK_dcmimgle_LIBRARY dcmimgle ${DCMTK_DIR}/dcmimgle/libsrc ${DCMTK_DIR}/dcmimgle/libsrc/Release ${DCMTK_DIR}/dcmimgle/libsrc/Debug ) Shouldn't FIND_LIBRARY look in the "release" and "debug" subfolders by default? It does not seem to.
