+# FindCurses
+# ----------
+#
+# 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.
+#
+# 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:
+#
+# ``CURSES_INCLUDE_DIR``
+# Path to Curses include. Use ``CURSES_INCLUDE_DIRS`` instead.
+# ``CURSES_LIBRARY``
+# Path to Curses library. Use ``CURSES_LIBRARIES`` instead.

+# If wsyncup is in curses, use this one.
+# If not, try to find ncurses and check if this has the symbol.
+# Once the ncurses library is found, search the ncurses.h header first, but
+# some web pages also say that even with ncurses there is not always a ncurses.h:
+# http://osdir.com/ml/gnome.apps.mc.devel/2002-06/msg00029.html
+# So at first try ncurses.h, if not found, try to find curses.h under the same
+# prefix as the library was found, if still not found, try curses.h with the
+# default search paths.
