# $NetBSD: curses.buildlink3.mk,v 1.26 2017/03/20 00:30:30 roy Exp $
#
# This Makefile fragment is meant to be included by packages that require
# any curses implementation instead of one particular one. The available
# curses implementations are "curses" if built-in, "ncurses", and
# "pdcurses".
#
# If a package genuinely requires ncurses or pdcurses, then it should
# directly include the appropriate buildlink3.mk instead of this file in
# the package Makefile.
#
# === User-settable variables ===
#
# CURSES_DEFAULT
# This value represents the type of curses we wish to use on the
# system. Setting this to "curses" means that the system curses
# implementation is fine.
#
# Possible: curses, ncurses, ncursesw, pdcurses
# Default: (depends)
#
# === Package-settable variables ===
#
# USE_CURSES
# This value represents the features the package needs from curses.
# If the system curses does not provide those features, then
# a more suitable curses is pulled in (normally ncurses).
#
# Possible: wide
# For more possible values, see curses.builtin.mk.
# Default: (unset)
#
# FAKE_NCURSES
# Some packages look exclusively for ncurses or ncursesw,
# headers and libraries. This really is an error with the package,
# but patching it can be both challenging and cumbersome.
# Set this to YES to transform these to system curses.
#
# Possible: YES, NO
# Default: NO
#
# INCOMPAT_CURSES
# If no test exists the missing curses feature then set this
# to match the platform where system curses isn't suitable.
# This can include the case where the system curses compiles fine,
# but for some reason fails to work.
#
# Default: (unset)
#
# === Variables set by this file ===
#
# CURSES_TYPE
# The name of the selected curses implementation.
