There already is such support: you can configure subprojects to live in
an arbitrary location by setting the `subproject_dir` parameter in the
`project()` call. But there are some restrictions in place here:

  - It cannot be an absolute path.

  - It must not start with a dot.

  - It must not contain "../".

So that means it's not possible to specify the top-level directory, and
that seems to be a concious decision.
