I know this question has been asked before, but before you redirect me to an already existing thread, read the answers and see how vague or even completely unhelpful they’re. I am just trying to find out all the libraries used to make Unreal Engine, is there a place on the official website that lists it’s various libraries and components? Or does somebody actually know for sure what libraries Unreal Engine 4 uses?

Thanks a lot!
