error C4430: missing type specifier when compiling project using GDExtension cpp bindings

I’m making a small project using GDExtension’s cpp bindings (the idea is to reuse some cpp code I have to make it usable inside Godot)

When I’m compiling, however, I get the following error message (on Visual Studio 2019):

Error C4430: missing type specifier - int assumed. Note: C++ does not support default-int

I’m getting this error on the file godot-cpp/variant/vector2.hpp at the following line:

Vector2 min(const Vector2 &p_vector2) const {
	return Vector2(MIN(x, p_vector2.x), MIN(y, p_vector2.y));

From my understanding this means that the compiler can’t recognize the Vector2 definition as a valid type. This function is defined inside the Vector2 struct

What’s happening here?

The min and max functions in vector2.hpp are hexed. Comment them out and implement the functionality yourself if you have to.
