First hit I get is https://learnopengl.com/Advanced-OpenGL/Cubemaps​

Given that it's a site for learning OpenGL, there is an example there with a cubemap and everything gets explained, so you can change everything and more as you desire.

I haved solved this by setting the texture coordinate position as the vertex position inside the vertex shader!
