Ahhh, right, thanks. My current hack would not work as expected if I switch
to another project and compile that without first killing the previous
*compilation* buffer, since it would have the previous project settings. So
to be project aware I guess I would somehow need to set the
compilation-search-path from compilation-start-hook?

Do you mean all directories for the current project, or all directories
across all projects? If the former, that's exactly what I want. If the
latter, that seems prone to incorrectly resolving the source file for a
message as coming from a project other than the current (particularly for
generic filenames like "utils.c") and additionally I try not to have
anything project specific in my global emacs init, they should live in the
project repo (and .dir-locals.el is the only mechanism I'm aware of for
that).

Cheers,
Len.
