#.rst:
# FindNcursesw
# ------------
#
# Find the ncursesw (wide ncurses) include file and library.
#
# Based on FindCurses.cmake which comes with CMake.
#
# Checks for ncursesw first. If not found, it then executes the
# regular old FindCurses.cmake to look for for ncurses (or curses).
#
#
# Result Variables
# ^^^^^^^^^^^^^^^^
#
# This module defines the following variables:
#
# ``CURSES_FOUND``
# True if curses is found.
# ``NCURSESW_FOUND``
# True if ncursesw 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_HAVE_NCURSESW_NCURSES_H``
# True if ``ncursesw/ncurses.h`` is available.
# ``CURSES_HAVE_NCURSESW_CURSES_H``
# True if ``ncursesw/curses.h`` is available.
#
# Set ``CURSES_NEED_NCURSES`` to ``TRUE`` before the
# ``find_package(Ncursesw)`` call if NCurses functionality is required.
