Remove include and lib folders removed since 3.0.0 core by maxgerhardt · Pull Request #8125 · esp8266/Arduino (original) (raw)

Synchronizes the platformio-build.py build script with what is actually there in the core folder. The folder tools/sdk/libc was removed since core version 3.0.0, (but existed in 2.7.4), however the script was not updated.

This makes users unsure as there is warning about this not-found directory in VSCode then (source).

Fixed by simply removing the non-existant folders from the build script.
