I was looking into something like this in order to port a POSIX-only program to run on Windows. Does anyone know how to link in native OpenGL system libraries?

I was looking into something like this in order to port a POSIX-only program to run on Windows. Does anyone know how to link in native OpenGL system libraries? I'm looking to link to native graphics libraries so that I don't have to pass through Emscripten's OpenGL -> WebGL emulation layer. I'd like to drop the browser render layer all together and just have GLFW or SDL take care of rendering native client windows.
