Include errors in esp32 project

I want to include a header of my include folder in the file in the lib folder.

The project folder’s include/ folder is by default not visible to libraries in lib/. You have to explicitly say so.

I have exactly the same problem. I thought that the include directory would be the place to put “global” include files, however that doesn’t seem to work. What is the way to do this?
