| # Find the curses include file and library |
| # |
| # |

| # :: |
| # |
| # CURSES_FOUND - system has Curses |
| # CURSES_INCLUDE_DIR - the Curses include directory |
| # CURSES_LIBRARIES - The libraries needed to use Curses |
| # CURSES_HAVE_CURSES_H - true if curses.h is available |
| # CURSES_HAVE_NCURSES_H - true if ncurses.h is available |
| # CURSES_HAVE_NCURSES_NCURSES_H - true if ncurses/ncurses.h is available |
| # CURSES_HAVE_NCURSES_CURSES_H - true if ncurses/curses.h is available |
| # CURSES_LIBRARY - set for backwards compatibility with 2.4 CMake |
| # |
| # |
| # |
| # Set CURSES_NEED_NCURSES to TRUE before the find_package() command if |
| # NCurses functionality is required. |
