asterisk users - Apr 2008 - compilation of asterisk 1.4.19 with ilbc already on system

I already have ilbc installed on my system. The files
are:

/usr/include/ilbc/iLBC_decode.h
/usr/include/ilbc/iLBC_define.h
/usr/include/ilbc/iLBC_encode.h
/usr/lib/libilbc.a
/usr/lib/libilbc.la
/usr/lib/libilbc.so -> libilbc.so.0.0.0
/usr/lib/libilbc.so.0 -> libilbc.so.0.0.0
/usr/lib/libilbc.so.0.0.0

However, if I do a "make" in asterisk-1.4.19, it will
not detect that libilbc.a is already on the system. If
I manually remove "codec_ilbc" from MENUSELECT_CODECS
in menuselect.makeopts then codecs/codec_ilbc.c will
compile to codec_ilbc.o because it finds the header
files (/usr/include/ilbc/iLBC_{en,de}code.h) but it
will fail to compile to codec_ilbc.so because it will
try to make the ilbc subdir which I haven't downloaded
the ilbc source code to.

How can I tell the make system in 1.4.19 that ilbc is
already on the system and that it should link to
/usr/lib/libilbc.a?

Shouldn't the configure script do that?

No; the Asterisk build system has never had support for using a
system-provided version of the iLBC library.

Whoever provided you that library could easily run afoul of the same
licensing issues that caused us to remove the code from our Asterisk
distribution, and using that library does not obviate you from the need
to register your intent to use the codec if you are using it for
commercial purposes.
