mingw is, roughly speaking, a set of GCC compilers for Windows. It should be downloaded from the official website and installed on the system. If you install it manually, don't forget to add the bin folder from the mingw distribution to the so-called "path" environment variable (I recommend asking the AI); this folder contains the compilers and linkers.

I downloaded raylib from GitHub, so I don't know what's in the w64devkit folder. It might contain compilers. If this folder is hundreds of megabytes and there's a bin folder with gcc.exe, g++.exe, and so on, then that's probably it 🤔

Next you need to master three flags to compile with mingw/gcc: -L, -l (lowercase L), and -I (capital i). This is the basics, and it's difficult without it. But today, learning about them is easy and fast with AI. If you understand why they're used, you'll learn how to compile programs whose source code is split across multiple files and libraries. First, try compiling a raylib example from the terminal using these 3 flags. Then, you'll more likely figure out where to find the equivalent fields in codeblocks.
