godotengine/godot ? reverse-engineered prompt

I'd like you to build the Godot game engine from this source code. The goal is a complete, runnable application that I can use to create both 2D and 3D games. It should be the full, feature-packed editor with its unified interface and all the common tools, so I can start making a game without having to build everything from scratch.

A really important feature is being able to export games to all the major platforms like Windows, macOS, Linux, Android, iOS, and even for the web, ideally with a single click. I know this is a huge C++ project, so please figure out the entire compilation process and any dependencies needed. You should probably look at the official docs to see the recommended way to build it from source. The final result should be the Godot editor program, ready to launch.
