Wtf does this do

This repository contains a developer's personal work following the tutorials at learnopengl.com, a popular free resource for learning how to create 3D graphics. The project represents a hands-on learning journey rather than a finished tool or application. OpenGL is a widely used programming interface that lets software communicate with a computer's graphics hardware to render 2D and 3D graphics. The tutorials being followed walk through concepts like drawing shapes, applying textures and lighting, and building the fundamentals of a 3D rendering engine. The code here is written in C, which is one of the common languages used for this type of low-level graphics programming. Someone who would look at this code is likely a fellow learner or a beginner curious about how 3D graphics actually work under the hood. Rather than using a pre-built game engine like Unity or Unreal, this approach teaches the foundational mechanics: how individual pixels get drawn to the screen and how light is calculated in a virtual scene. The README doesn't go into detail, which is expected for a personal study project. There are no setup instructions, usage guides, or descriptions of how far along the author is in the tutorial series. Anyone wanting to run or build the code would need to be familiar with compiling C projects and linking the necessary graphics libraries on their own.

Yoink these prompts

Prompt 1
I am following the learnopengl.com tutorials in C. Help me set up a basic C project that links OpenGL, GLFW, and GLAD so I can compile and run tutorial code on my machine.
Prompt 2
Show me how to write a minimal C program using OpenGL that draws a colored triangle to the window, similar to the first learnopengl tutorial.
Prompt 3
Explain how lighting works in OpenGL and help me implement a simple Phong lighting model in C following the learnopengl.com lighting tutorial.
Prompt 4
I have C code from following learnopengl tutorials but no build system. Help me create a Makefile or CMakeLists.txt to compile my OpenGL project with the correct library linking flags.
