It should be possible to integrate into Godot, since it has a C++ SDK. You could probably make it work with GDNative, and if that does not work then you could certainly make it work as a module.
I do not think it would be supported offically though, due to it’s software license not really being compatible with Godot’s (or at least, not based on what I could see). Anyone can make a unofficial GDNative/module implementation though!
