# This Makefile fragment is included by packages that use ncurses.
#
# To use this Makefile fragment, simply:
#
# (1) Optionally define USE_NCURSES to force use of ncurses,
#     or define INCOMPAT_CURSES to specify NetBSD versions that are
#     missing some needed functions.
# (2) Optionally define BUILDLINK_DEPENDS.ncurses to the dependency pattern
#     for the version of ncurses desired.
# (3) Add ${BUILDLINK_INCDIR} to the front of the C preprocessor's header
#     search path, and
# (4) Add ${BUILDLINK_LIBDIR} to the front of the linker's library search
#     path.
