Hello @olegharput, welcome.

First of all, which Linux Distribution are you using? Often is available as a system package.

In debian like distributions you can call

sudo apt install libsdl2-dev

Anyhow, you can follow up Lazyfoo’s tutorial, in first lesson heexplains how to get SDL working in your system.
