It's a bit quiet on the Matrix side today (I think the bridge is down), so I'll
try and ask my question here 🙂

TL;DR: how do I import a local nimble package from another local nimble
package?

I have a monorepo with two different nimble packages, in sibling directories. I
want to import one from the other.
I can make it work by adding the source directory of one to the other with
`--path:`, but then I also have to specify all of the one package's dependencies
in the .nimble file of the other package.

I'd much prefer having a "proper" dependency tree, but I cant figure out how to
refer to one local nimble package from another local nimble package.
