Absolutely.  In the example you gave, that was the case.

There is no way that is not a "hack", for some definition of that word,
to do this in the case where the names are not related.

You have to do something like this:

  foo: .gen_abc_def
          <commands that use abc and def>

  .gen_abc_def: <prerequisites of abc and def>
          <build abc and def>
          @touch $@
