msbuild compile error: uses undefined class 'std::array<int,2>

When I build the forge using msbuild, I get the following error.

I don't know what I'm doing wrong.

add #include <array> to src\backend\opengl\glfw\windows.hpp could fix the problem

I am not sure how that header is relevant to glfw/window.hpp. There doesn't seem to be any declaration of that type in that window header.
