# - Find OpenJPEG library
# Find the native OpenJPEG includes and library
# This module defines
# OPENJPEG_INCLUDE_DIRS, where to find openjpeg.h, Set when
# OPENJPEG_INCLUDE_DIR is found.
# OPENJPEG_LIBRARIES, libraries to link against to use OpenJPEG.
# OPENJPEG_ROOT_DIR, The base directory to search for OpenJPEG.
# This can also be an environment variable.
# OPENJPEG_FOUND, If false, do not try to use OpenJPEG.
#
# also defined, but not for general use are
# OPENJPEG_LIBRARY, where to find the OpenJPEG library.
