# This Makefile fragment is included by packages that use getopt_long().
#
# 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_DIR}/include to the front of the C preprocessor's header
#     search path.
# (4) Add ${BUILDLINK_DIR}/lib to the front of the linker's library search
#     path.
