#
# SYNOPSIS
#
# MP_WITH_CURSES
#
# DESCRIPTION
#
# Detect SysV compatible curses, such as ncurses.
#
# Defines HAVE_CURSES_H or HAVE_NCURSES_H if curses is found. CURSES_LIB
# is also set with the required libary, but is not appended to LIBS
# automatically. If no working curses libary is found CURSES_LIB will be
# left blank.
#
# This macro adds the option "--with-ncurses" to configure which can force
# the use of ncurses or nothing at all.
