# This Makefile fragment is included by packages that use X11.  It's
# only purpose is to make a package strongly buildlinked, so packages
# that include this file must already satisfy the requirements for
# USE_BUILDLINK_ONLY.
#
# To use this Makefile fragment, simply:
#
# (1) Optionally define USE_BUILDLINK_X11 to use pkgtools/buildlink-x11
#     to cause packages that use imake to use buildlink, and
# (2) Include this Makefile fragment in the package Makefile.
#
# NOTE: This file must be included _before_ bsd.pkg.mk.
# NOTE: This file should _not_ be included in any package's buildlink.mk file.
