Another way to write this would be:

   LIB_OBJS += $(patsubst %.c,%.o,$(wildcard $(addsuffix /*.c,$(LIB_OBJS_DIRS)))

I don't know that there's any reason to choose one over the other. I don't think there's any real performance difference although one could imagine this version to be VERY SLIGHTLY faster. Also this one is a little more "Lisp-ish"... that might be a pro or a con depending :).

Just kibitzing while waiting for dinner to arrive...
