No, this is CPU rendering only! Not even SIMD, just straightforward integer (and float) code.
If its OpenGL why is it CPU only ?

OpenGL is an API. Software renderers for it—like the one that originally came with Windows NT, or even early versions of Mesa—have been out for a long time.

Raylib's author was very happy to announce that you can compile an entire raylib program with no dependencies other than, say, being a win32 app https://x.com/raysan5/status/1980322289527976202
but ... why?

As someone who was once a child trying to figure out how to compile and link things to use SDL, I think there's some educational value in letting people make games without having to dive deep into how to use C++ toolchains.
If you want to do that, skip C++ entirely and just use Javascript or Python. You can get shiny things really quickly.
This will be perfect for Nintendo 3DS!

Cool project, and fun to play with.
What's cool about this is that computers are so fast that you could probably make a decent 2D game using only this software-rendered OpenGL 1.1 library.
Ha! That’s what I’m stuck with for Metropolis 1998. I have to use the ancient OpenGL fixed function pipeline (thankfully I discovered an AB extension function in the gl.h file that allows addition fields to be passed to the GPU).
I’m using SFML for the graphics framework which I think is OpenGL 1.x
