I don't see how can GDB do what you want; perhaps I'm missing
something.

The debug info recorded in the executable says that one of the source
files is ../foo/bar/baz.c.  How can GDB know that a file you are
visiting, whose absolute file name is /home/user/project/foo/bar/baz.c,
is that file?

What I suggested is to tell GUD that the project directory is
/home/user/project/build.  Armed with that knowledge, we could modify
GUD to produce a file name relative to /home/user/project/build, and
the result will allow GDB to identify that file in its data base.
