Thank you for your PR. The problem I see is that it will only work for Debian based system, I don't know if there is a way to do this in a more portable way however.

I think we can check if it's debian, arch or something else with this:

I'll try to work on it later, but I don't have arch based distro or anything else but I'll see.

I like the motivation behind install.sh keeping everything as simple as possible for new users but I think information about how to install dependencies is best suited for the README. In there we could include instructions for using apt, yum, brew, etc to grab SFML.
