Q about include files

I’m using a library (lwip) which includes a file (lwipopts.h) that is not part of that library. This is intentional, as this is where you set configuration options.

I’m placing the library in its own folder (lib/lwip/) and add a library.json file to make it play nice in the PIO context.

Where do I place my include file? Whatever I try, the file is not found.

(I don’t want to place it inside the library, because it’s app-specific)

Create a new directory called config within the lib folder and put it there. That should work.

Ok, I misunderstood. Yes, that should do the trick, thank you.
