If the external makefile generates a library, I think you can just
deal with the library itself and not all the objects generated by
building the library.  So, use the "output" specifier of the
add_custom_command() to give the name of the library, not all the
object files.  Be warned though, that if you change a source file
covered only by the external makefile, your project will not rebuild
properly.

Sounds like what you want is to identify the libraries produced by the
external makefile as a first class target usable by other parts of
your build, but this is the problem!  I don't think cmake has a
succinct way to do this.  Would love to hear otherwise.
