These have been renamed, in keeping with +# AX_WITH_CURSES's close bigger brother, PKG_CHECK_MODULES, which should +# eventually supersede the use of AX_WITH_CURSES. Neither the library +# listed in CURSES_LIBS, nor the flags in CURSES_CFLAGS are added to LIBS, +# respectively CPPFLAGS, by default. You need to add both to the +# appropriate xxx_LDADD/xxx_CPPFLAGS line in your Makefile.am. For +# example: +# +# prog_LDADD = @CURSES_LIBS@ +# prog_CPPFLAGS = @CURSES_CFLAGS@ +# +# If CURSES_LIBS is set on the configure command line (such as by running +# "./configure CURSES_LIBS=-lmycurses"), then the only header searched for +# is .

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 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.
