# - find DCMTK libraries and applications
#

##
## THIS FILE WAS MODIFIED TO MATCH THE REQUIREMENTS OF CMTK
##
## - only DCMTK libraries are tested and configured that are actually used by CMTK
##
##

#  DCMTK_INCLUDE_DIRS   - Directories to include to use DCMTK
#  DCMTK_LIBRARIES     - Files to link against to use DCMTK
#  DCMTK_FOUND         - If false, don't try to use DCMTK
#  DCMTK_DIR           - (optional) Source directory for DCMTK
#  DCMTK_DCMDICTPATH   - Path to dicom.dic data dictionary
#
# DCMTK_DIR can be used to make it simpler to find the various include
# directories and compiled libraries if you've just compiled it in the
# source tree. Just set it to the root of the tree where you extracted
# the source (default to /usr/include/dcmtk/)
