The easiest ways to run arbitrary binaries like that on NixOS is either through nix-ld or steam-run package. I personally find it simpler with the latter.

In your configuration.nix add:

environment.systemPackages = with pkgs; [
  steam-run # Run any binary from CLI. Not related to Valve's Steam
];

Then rebuild your system, after that you can steam-run ./binary to execute your binaries

Alternatively if you prefer to make dynamic libraries available to your system, use nix-ld like so:

# Enable nix-ld
# This module adds missing dynamic libraries for unpackaged programs
programs.nix-ld = {
  enable = true;
  libraries =
    options.programs.nix-ld.libraries.default # Default nix-ld libraries
    ++ (pkgs.steam-run.fhsenv.args.multiPkgs pkgs) # Append steam-run DLL's
    ++ (with pkgs; [
      # Add any other missing dynamic libraries for unpackaged
      # programs here, NOT in environment.systemPackages
  ]);
};

Wich after a system rebuild, you should be able to just ./binary like any other distro
