Nix
---
As an alternative to getting the prerequisites yourself, you can use Nix/NixOS and run the following to get dropped into a shell with nextpnr built:
nix-shell
Or, you can add the `nextpnr.nix` file into your /etc/nixos/configuration.nix:
environment.systemPackages = [
...
( import /home/q3k/Software/nextpnr/nextpnr.nix )
...
];
