# $NetBSD: buildlink.mk,v 1.5 2001/05/26 05:44:09 jlam Exp $
#
# This Makefile fragment is included by packages that use getopt_long().
#
# If getopt_long() is not present in the base system, then a dependency
# on devel/libgetopt is added, and the appropriate headers are linked
# into ${BUILDLINK_INCDIR} (${WRKDIR}/include).
#
# To use this Makefile fragment, simply:
#
# (1) Include this Makefile fragment in the package Makefile,
# (2) Optionally define BUILDLINK_INCDIR and BUILDLINK_LIBDIR,
# (3) Add ${BUILDLINK_TARGETS} to the prerequisite targets for pre-configure,
# (4) Add ${BUILDLINK_INCDIR} to the front of the C preprocessor's header
# search path.
# (5) Add ${BUILDLINK_LIBDIR} to the front of the linker's library search
# path.
