Issues in compilation

[vesar-github]

Hi!

I got quoted errors in compilation. I'm just a beginner in this ESP32-world, but with a little help from Google, at least this breaking change probably should be fixed in code? espressif/arduino-esp32#8724

Other errors said even less to me.

Regarding the errors related to included libraries, I tried with both latest versions of the libraries and the ones referred to in your setup guide.
