+You can install C libraries by copying their files to 3 locations. Then you will be able to include the headers in your project files, and compile in w64devkit with the `-l` flag followed by the name of the installed library.

+- Copy headers (.h or .hpp) to `C:\raylib\w64devkit\x86_64-w64-mingw32\include\`
+- Copy libraries (.lib) to `C:\raylib\w64devkit\x86_64-w64-mingw32\lib\`
+- Copy executables (.dll or .exe) to `C:\raylib\w64devkit\bin\`
