It happened to me now several times, that a library needs a configuration file in order to work. This file has to be created by user and it’s not included in the library itself. The problem is, that PlatformIO doesn’t see header files that are referenced by the library, but are present in the proje…

That’s intentional, include and src folders are not global and only visible to project sources (not libraries or frameworks). If you need this include globally specify it in build_flags: build_flags = -I include

PIO library doesn't see header files in project's include folder

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?

PIO compiler says no such file or directory when file clearly exists
