Turborepo with Aurlia / Aurelia Plugins

I would like to maintain a larger Aurelia application in a Turborepo. There are several Aurelia applications in the apps section and packages should contain shared Aurelia plugins and other typescript code.

When the repo is started, the Aurelia plugins are built and should be available, but the controls are not found by the main application (their html files).

I have a small example with an Aurelia application and a plugin on Github. Maybe someone has a solution for the problem.

If I pack it with the CLI bundler, then it works. But then I can’t use the finished bundle with Single Spa (I think because the target is not system).
