Jupp: This is definitely a question to be answered by a Qt mailing
list. It has nothing to do with gcc. Even make is not a part of gcc,
so that likely has its own mailing list as well.
Corey: If you are linking an executable against a static library, as
Jupp is doing, you must re-link the executable if the library changes,
otherwise your executable will NOT see the changes made in the library.
This is definitely something you would do in a Makefile for your
executable, probably something like this:
executable: main.o staticlibrary.a
LINK_COMMAND_HERE
That rule would trigger a re-link of the executable if either main.o or
staticlibrary.a were changed.

Well, I don't exactly see why you would want that.
However, that's an automake, make issue. I'm not sure if you can
specify a binary in the dependency list though.
