AC_SUBST on xxx_LDADD

[Davy Durham]

Hey, problem,

I'm using a @ABC@ directive in the xxx_LDADD value in my Makefile.am

I conditionally build a convenience library depending on what's found 
during configure.  So I either set ABC to something if I'm going to 
build the lib or set it to nothing if not.

However when the xxx_DEPENDENCIES value is generated in Makefile.in (and 
of course on to Makefile) the substituted value is never included (and 
the @ABC@ is missing as well, not as if it just didn't get substituted 
by the AC_SUBST).

Is this a know issue?  Is there a work-around?  Currently I'm just 
editing the Makefile and adding what's necessary to the xxx_DEPENDENCIES 
value.  If I don't then changing source in the lib doesn't cause the 
main application to re-link even though the lib is rebuilt (because of 
the changed source).

If you care to look at source...
http://cvs.sourceforge.net/viewcvs.py/rezound/rezound/
./configure.ac  -- MAYBE_LADSPA_LIB is the ABC of @ABC@ above
./src/frontend_fox/Makefile.am contains the use of @ABC@ in rezound_LDADD
./src/backend/LADSPA is the directory of the lib that might or might not 
be built.
[Note: I'm *just* checking this in and sourceforge's anonymous CVS stuff 
may be a little slow to update]

Thanks,
  Davy
