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_CFLAGS``
|
||
|
Parameters which ought be given to C/C++ compilers when using 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.
|
||
|
Set ``CURSES_NEED_WIDE`` to ``TRUE`` before the
|
||
|
``find_package(Curses)`` call if unicode 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 NCurses is required, use the function wsyncup() to check if the library
|

# has NCurses functionality (at least this is where it breaks on NetBSD).
|

|
# If wsyncup is in curses, use this one.

# 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.
