lib/Makefile.am (Nicolas Boullis):

Browse Source 
Mostly some cleanup... First, this tries to keep the versioning
separated from the rest of the Makefile. I used the "foo := $(foo)
bar" syntax rather than "foo += bar" as I think the += is not
available on all versions of make.

Moreover, I replaced "$(LIBCDIO_LIBS)" with "libcdio.la" as
"$(LIBCDIO_LIBS)" is "../lib/libcdio.la". That make a difference if you
try to build libiso9660.la while libcdio.la is not available. Make knows
how to make libcdio.la but not ../lib/libcdio.la.
