# $FreeBSD$
#
# handle dependency on the ncurses port
#
# Feature:	ncurses
# Usage:	USES=ncurses
# Valid ARGS:	base port
#
# use/port can now set this options to the makefiles
# NCURSES_RPATH= yes	- pass RFLAGS options to CFLAGS
#
# Overridable defaults:
# NCURSES_PORT=	devel/ncurses
#
# The makefile sets the following variables:
# NCURSESBASE		- "/usr" or ${LOCALBASE}
# NCURSESLIB		- path to the libs
# NCURSESINC		- path to the matching includes
# NCURSESRPATH		- rpath for dynamic linker
#
# BUILD_DEPENDS		- are added if needed
# RUN_DEPENDS		- are added if needed
