# 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
|
||||
# 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(Curses)`` call if NCurses functionality is required.
|
||||
#
|
||||
# Backward Compatibility
|
||||
# ^^^^^^^^^^^^^^^^^^^^^^
|
||||
#
|
||||
# The following variable are provided for backward compatibility:
|
||||
#
|
||||
# Set CURSES_NEED_NCURSES to TRUE before the find_package() command if
|
||||
# NCurses functionality is required.
|
||||
# ``CURSES_INCLUDE_DIR``
|
||||
# Path to Curses include. Use ``CURSES_INCLUDE_DIRS`` instead.
|
||||
# ``CURSES_LIBRARY``
|
||||
# Path to Curses library. Use ``CURSES_LIBRARIES`` instead.
