Based on https://github.com/transmutrix/nim-sdl3 but heavily modified to use idiomatic Nim names.
How to install the required SDL 3 binaries.
These commands work for Ubuntu. Other distros have their own ways:
sudo apt install libsdl3-0
sudo apt install libsdl3-dev
sudo apt install libsdl3-ttf-dev
sudo apt install libsdl3-image-dev
sudo apt install libsdl3-mixer-dev
Via brew:
brew install sdl3
brew install sdl3_ttf
brew install sdl3_mixer
To be determined.
