Not sure how to solve non-Haskell dependency issue

[jerbaroo]

Perhaps consider this a documentation issue. I have tried each of the snippets in https://input-output-hk.github.io/haskell.nix/tutorials/pkg-map.html.

The issue is that the HDBC-sqlite3 Haskell package expects to find sqlite3, but in my nixpkgs it is known merely as sqlite:

       … while evaluating the option `packages.HDBC-sqlite3.components.library.libs':

       … while evaluating definitions from `/nix/store/kdba7yxld9fk2ds8yirq0w53g5ky1m1a-haskellNix-src/modules/plan.nix':

       (stack trace truncated; use '--show-trace' to show the full, detailed trace)

       error: The Nixpkgs package set does not contain the package: sqlite3 (system dependency).
       You may need to augment the system package mapping in haskell.nix so that it can be found.

Here are my current nix files:

# packages.nix
let
  sources = import ./nix/sources.nix {};
  haskellNix = import sources.haskellNix {};
  pkgs = import haskellNix.sources.nixpkgs-unstable haskellNix.nixpkgsArgs;
in pkgs

# default.nix
let
  pkgs = import ./packages.nix;
in pkgs.haskell-nix.project {
  src = pkgs.haskell-nix.haskellLib.cleanGit {
    name = "advent";
    src = ./.;
  };
}

# shell.nix
let
  pkgs = import ./packages.nix;
  project = import ./default.nix;
in project.shellFor {
  exactDeps = true;
  buildInputs =  [ pkgs.ghcid ];
  tools = {
    cabal = "latest";
    haskell-language-server = "latest";
  };
  withHoogle = false;
}
