what i meant was the following (examples from our configure.ac):
if AST_EXT_LIB_SETUP([IKSEMEL], [Iksemel Jabber Library], [iksemel])
says yes, it means that iksemel itself links without extra libs,
otherwise we would have used something like this
AST_EXT_LIB_CHECK([OSPTK], [osptk], [OSPPCryptoDecrypt], [osp/osp.h], [-lcrypto
-lssl])
i.e. tell it what extra libs we need.
I modified the macro (which is "our code", in acinclude.m4)
to support multiple instances and stop at the
first matching one e.g.
AST_EXT_LIB_CHECK([TONEZONE], [tonezone], [tone_zone_find],
[zaptel/tonezone.h], [${tonezone_extra}], [140])
# other case, old tonezone (0.80)
AST_EXT_LIB_CHECK([TONEZONE], [tonezone], [tone_zone_find], [zaptel/zaptel.h],
[${tonezone_extra}], [80])
cheers
