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.
