Dependencies between projects with Haskell Stack build tool — best workflow?

Question

I am just beginning a relatively large Haskell project using the stack package manager and build tool, and I am trying to figure out the best way to split it up into several stack projects with dependencies between them.

Essentially, while I believe I understand how to use stack to include external packages downloaded from Stackage in my project, I don't understand how to include packages from other local projects. How do I create libraries using stack that I can then use in other projects?

In stack.yaml there is the field packages . This is where you can specify the locations of other projects.

For an example, see the stack.yaml file for the hayoo repo:
