0001 # - Find LCMS
0002 # Find the LCMS (Little Color Management System) library and includes and
0003 # This module defines
0004 #  LCMS_INCLUDE_DIR, where to find lcms.h
0005 #  LCMS_LIBRARIES, the libraries needed to use LCMS.
0006 #  LCMS_DOT_VERSION, The version number of the LCMS library, e.g. "1.19"
0007 #  LCMS_VERSION, Similar to LCMS_DOT_VERSION, but without the dots, e.g. "119"
0008 #  LCMS_FOUND, If false, do not try to use LCMS.
0009 #
0010 # The minimum required version of LCMS can be specified using the
0011 # standard syntax, e.g. find_package(LCMS 1.10)
