disabling "warnings being treated as errors"

Hello,

I installed the dabbleESP32-library with the library-manager and tried to compile the example 02.-terminal.ino
The compiler terminated with lot's of warnings and the final message
cc1plus.exe: some warnings being treated as errors

I know I shouldn't ignore warnings. Yes I want the compiler to tell me warnings but I don't want the compiler terminate just because of warnings. What do I have to change to make the compiler treating warnings as warnings without terminating?

As I'm a nooby about c++-compiler if you could provide a link to a tutorial that explains all the steps in detail I would be very thankful.

best regards

Stefan
