# SYNOPSIS
#
#   AX_WITH_CURSES_PANEL
#   AX_WITH_CURSES_MENU
#   AX_WITH_CURSES_FORM
#
# DESCRIPTION
#
#   These macros try to find additional libraries that often come with
#   SysV-compatible Curses.  In particular, the Panel, Menu and Form
#   libraries are searched, along with their header files.  These macros
#   depend on AX_WITH_CURSES.
#
#   The following preprocessor symbols may be defined by these macros:
#
#     By AX_WITH_CURSES_PANEL:
#
#     HAVE_PANEL              - if the Panel library is present
#     HAVE_PANEL_H            - if <panel.h> is present and should be used
#     HAVE_NCURSES_PANEL_H    - if <ncurses/panel.h> should be used
#     HAVE_NCURSESW_PANEL_H   - if <ncursesw/panel.h> should be used
#
#     By AX_WITH_CURSES_MENU:
#
#     HAVE_MENU               - if the Menu library is present
#     HAVE_MENU_H             - if <menu.h> is present and should be used
#     HAVE_NCURSES_MENU_H     - if <ncurses/menu.h> should be used
#     HAVE_NCURSESW_MENU_H    - if <ncursesw/menu.h> should be used
#
#     By AX_WITH_CURSES_FORM:
#
#     HAVE_FORM               - if the Form library is present
#     HAVE_FORM_H             - if <form.h> is present and should be used
#     HAVE_NCURSES_FORM_H     - if <ncurses/form.h> should be used
#     HAVE_NCURSESW_FORM_H    - if <ncursesw/form.h> should be used
#
#   The following output variables may be defined by these macros; these are
#   precious and may be overridden on the ./configure command line:
#
#     PANEL_LIB   - library to add to xxx_LDADD before CURSES_LIB
#     MENU_LIB    - library to add to xxx_LDADD before CURSES_LIB
#     FORM_LIB    - library to add to xxx_LDADD before CURSES_LIB
#
#   These libraries are NOT added to LIBS by default.  You need to add them
#   to the appropriate xxx_LDADD line in your Makefile.am in front of the
#   equivalent CURSES_LIB incantation.  For example:
#
#     prog_LDADD = @PANEL_LIB@ @CURSES_LIB@
#
#   If one of the xxx_LIB variables is set on the configure command line
#   (such as by running "./configure PANEL_LIB=-lmypanel"), then the header
#   file searched must NOT contain a subpath.  In this case, in other words,
#   only <panel.h> would be searched for.  The user may use the CPPFLAGS
#   precious variable to override the standard #include search path.
#
#   The following shell variables may be defined by these macros:
#
#     ax_cv_panel   - set to "yes" if Panels library is present
#     ax_cv_menu    - set to "yes" if Menu library is present
#     ax_cv_form    - set to "yes" if Form library is present
#
#   These variables can be used in your configure.ac to determine whether a
#   library you require is actually present.  For example:
#
#     AX_WITH_CURSES
#     if test "x$ax_cv_curses" != xyes; then
#         AC_MSG_ERROR([requires a SysV or X/Open-compatible Curses library])
#     fi
#     AX_WITH_CURSES_PANEL
#     if test "x$ax_cv_panel" != xyes; then
#         AC_MSG_ERROR([requires the Curses Panel library])
#     fi
#
#   To use the HAVE_xxx_H preprocessor symbols, insert the following into
#   your system.h (or equivalent) header file:
#
#     For AX_WITH_CURSES_PANEL:
#
#     #if defined(HAVE_NCURSESW_PANEL_H)
#     #  include <ncursesw/panel.h>
#     #elif defined(HAVE_NCURSES_PANEL_H)
#     #  include <ncurses/panel.h>
#     #elif defined(HAVE_PANEL_H)
#     #  include <panel.h>
#     #else
#     #  error "SysV-compatible Curses Panel header file required"
#     #endif
#
#     For AX_WITH_CURSES_MENU:
#
#     #if defined(HAVE_NCURSESW_MENU_H)
#     #  include <ncursesw/menu.h>
#     #elif defined(HAVE_NCURSES_MENU_H)
#     #  include <ncurses/menu.h>
#     #elif defined(HAVE_MENU_H)
#     #  include <menu.h>
#     #else
#     #  error "SysV-compatible Curses Menu header file required"
#     #endif
#
#     For AX_WITH_CURSES_FORM:
#
#     #if defined(HAVE_NCURSESW_FORM_H)
#     #  include <ncursesw/form.h>
#     #elif defined(HAVE_NCURSES_FORM_H)
#     #  include <ncurses/form.h>
#     #elif defined(HAVE_FORM_H)
#     #  include <form.h>
#     #else
#     #  error "SysV-compatible Curses Form header file required"
#     #endif
