I want to include a custom header file in my *.ino sketch using vs code. I have added ${workspaceRoot} to my includePath, but for some reason I am not able to compile the code.
Please see the build logs in Output path: /home/pheinrich/esp/ArduinoOutput

Including the header file with an absolute path is working.
