babel-macros preval.macro inside a dependency but evaluated at app build time

[watery]

From a SO question about How to show build datetime on my react web app using create-react-app? I found that preval.macro can be used to generate a fixed string during app build time.

I then created a component inside the app that makes use of preval.macro. And it worked.

Now I'm trying to make that component a bit more general, and I'd like to move it to a standalone package that other apps can add as dependency.

But there the macro fails with an error stating that the macro comes from undefined.

I commented on a babel-plugin-macros issue, thinking that I've encountered a similar problem. There I already received much help, though ending in that's not something that can be done.

I'd like to know if there's anything else I can try / edit (without ejecting tough) to accomplish my objective.
