The idea is the following: if libfoo.la is built by your package, then
you write:
  mylib_la_LIBADD = relative/path/to/in/tree/libfoo.la

and if it is built in the same directory, then you write:
  mylib_la_LIBADD = libfoo.la

If however it is installed by another package, then you write
  mylib_la_LIBADD = -lfoo

or something like
  mylib_la_LIBADD = @FOO_LIB@

where @FOO_LIB@ is computed by configure code you supply in
configure.ac, and typically may contain '-L/some/path' as well as
'-lfoo' entries.  There are existing Autoconf and third-party macros to
help with this computation.

Hope that helps.

Cheers,
Ralf
