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