COMP: ccmake requires ncurses, according to Berk and since it doesn't build
on NetBSD where there are separate curses and ncurses libraries, and where the curses library is found, which doesn't work for ccmake while the existing ncurses library would work. With this change it should be possible to test whether the found curses lib provides ncurses functionality. Alex
