I highly recommend you add all three configurations for each platform. It And the last thing to do, is to download the raylib binaries from the official
Raylib github repository. Just go to releases, and download the Microsoft

We are done. It should compile and run. Here's our raylib window.

Let's move on to the Mandelbrot Set. Mandelbrot fractal is basically a set of complex numbers, which are
constructed on a complex plane and which we will visualize in a 2D plane. As
a result, we get this amazing pattern.
So, how does it work? If you do some research you will find that Mandelbrot
set is a simple function of the form f(x) = z^2 + c, which we iterate
through starting from z = 0, where c is complex number that I will explain in
a moment.
The idea behind it is simple. We iterate throught the function and check
whether it's value vanishes at infinity. And then we draw each pixel based off
the result.
Here is an example:
