Better to use LIBADD always and never LDADD?

[cs]

For "convenience libraries" I just successfully
used LDADD.  It looks like LIBADD would also have
worked which uses LIBTOOL.....

I think LDADD is only for stuff you will *link*
with executable and LIBADD is more powerful and used
for other things like making real libraries you really
intend to install on system.

If true, wouldn't it be a good idea to get in habit
of using LIBADD (and Libtool) for everything?

i.e.
Why use 2 commands if 1 does both functions?
