# $NetBSD: Makefile.getopt,v 1.1 2001/05/15 19:18:14 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 ${WRKINCDIR} (${WRKSRC}/include).
#
# To use this Makefile, simply include this Makefile fragment in the
# package Makefile, optionally define WRKINCDIR, add
# link-getopt-headers to the prerequisite targets for pre-configure,
# and add ${WRKINCDIR} to the compiler's header search path.

# This target links the getopt header into ${WRKINCDIR}/include, which is
# searched first by the C preprocessor.
