ccmake: Check for curses more robustly before enabling
Compute a default for `BUILD_CursesDialog` by building a small test
project that uses curses. Disable `ccmake` by default if it fails,
and do not search for Curses as part of the main build. This avoids
creating FindCurses cache entries when we are not considering ccmake.
If `BUILD_CursesDialog` is enabled (e.g. by the user) then warn if
curses cannot be found.
