Dependencies in other folders for certain dev environments

[tclarke]

I've got a project that has dependencies on other internal projects in different repos. I have a local package repository available and I know how to specify the dependency and have it install from the repo. Is there a way I can have it install a local clone of the repo is available? This is useful if someone has WIP for both repositories or wants to use currently unreleased functionality. For example:

$MYPROJROOT/project1/pyproject.toml
$MYPROJROOT/project2/pyproject.toml

I'd like to specify the following as a default but is {root.parent}/project1 exists, use that instead.
dependencies = ["project1~=1.0.0"]
