You are ignoring the first sentence in my response, right?

The rest was a suggestion (and I do see a good reason why project.el
would like to provide this as a project-specific setting).

More generally, why would you want a directory-specific value for this
variable, if it isn't something the entire directory tree shares?

Maybe you should tell why you need to tell Emacs where to find the
sources?  Doesn't the tool you use to compile spell that out?
