Is my guess correct that it is looking for a system-installed mysql or mariadb instance?

Correct, the underlying SQL package requires that a system-level library for interfacing with the SQL server is installed. Hopefully this will be of help.

This project is a little bit of a mess as I've remade the project to use a ReactJS front-end. If you'd prefer to use this static version though feel free to let me know of any other issues you hit and I'll try to sort them out.
