How do bigger projects deal with C++ compile times?

@Tefel 120k lines of code in a single class? I mean holy ■■■■ I know that AAA games can get complex, but to me this just sounds wrong. It’s an example of how bad/hard managment can get if 100 people have to work with the same class I guess?. I’m pretty sure that everything is getting dumped into that base class for no good reason.
