# 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_LIBS - library to add to xxx_LDADD before CURSES_LIBS
# MENU_LIBS - library to add to xxx_LDADD before CURSES_LIBS
# FORM_LIBS - library to add to xxx_LDADD before CURSES_LIBS
#
# In previous versions of this macro, the flags PANEL_LIB, MENU_LIB and
# FORM_LIB were defined. These have been renamed, in keeping with the
# variable scheme of PKG_CHECK_MODULES, which should eventually supersede
# the use of AX_WITH_CURSES and AX_WITH_CURSES_* macros. 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_LIBS incantation. For example:
#
# prog_LDADD = @PANEL_LIBS@ @CURSES_LIBS@
#
# If one of the xxx_LIBS variables is set on the configure command line
# (such as by running "./configure PANEL_LIBS=-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
