I use the elisp code at

<http://git.hacks-galore.org/gitweb/jao?p=emacs.git;a=blob;f=custom/jao-compile.el;hb=master>

When one calls jao-compile on a source buffer, it looks upwards the
directory tree until it encounters a Makefile, or some other file
indicating that the top dir of the source has been found. Then it puts
itself in the right directory (where, in my case, 'right' means the
corresponding compilation directory, i.e., 'build' because i compile
off-tree).

Perhaps you could adapt the code above (its 'finding the right
directory' logic) to your needs.

HTH,
jao
