# FindCurses # FindCurses
# ---------- # ----------
# #
# Find the curses include file and library # Find the curses or ncurses include file and library.
# #
# Result Variables
# ^^^^^^^^^^^^^^^^
# #
# This module defines the following variables:
# #
# :: # ``CURSES_FOUND``
# True if Curses is found.
# ``CURSES_INCLUDE_DIRS``
# The include directories needed to use Curses.
# ``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_FOUND - system has Curses # Set ``CURSES_NEED_NCURSES`` to ``TRUE`` before the
# CURSES_INCLUDE_DIR - the Curses include directory # ``find_package(Curses)`` call if NCurses functionality is required.
# 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
# #
# Backward Compatibility
# ^^^^^^^^^^^^^^^^^^^^^^
# #
# The following variable are provided for backward compatibility:
# #
# Set CURSES_NEED_NCURSES to TRUE before the find_package() command if # ``CURSES_INCLUDE_DIR``
# NCurses functionality is required. # Path to Curses include. Use ``CURSES_INCLUDE_DIRS`` instead.
# ``CURSES_LIBRARY``
# Path to Curses library. Use ``CURSES_LIBRARIES`` instead.
