Im looking to install a custom package on heroku. I have the following folder structure.

├─ src
│  ├─ packagename
│  │  ├─ __init__.py
│  │  └─ ...
│  └─ setup.py
├─ tests
│  └─ ...
└─ Procfile

Locally I run the following to make the package structure importable.

$ cd src
$ pip install -e .

How do I add that step to build process in heroku?

The trick is to add it to the requirements.txt file with the -e flag. Found it out from looking at the docs on how to handle local file-backed distributions.
