#
# This Makefile fragment is meant to be included by packages that
# require a libjpeg implementation. jpeg.buildlink3.mk will:
#
# * set JPEGBASE to the base directory of the libjpeg files;
# * set JPEG_TYPE to the libjpeg implementation used.
#
# There are two variables that can be used to tweak the selection of
# the libjpeg implementation:
#
# JPEG_DEFAULT is a user-settable variable whose value is the default
# libjpeg implementation to use.
#
# JPEG_ACCEPTED is a package-settable list of libjpeg implementations
# that may be used by the package.
