Setup: No executables and no library found. Nothing to do.

This comes when running build on a derivation defined as:

let
  haskellNix = import (
    builtins.fetchTarball https://github.com/input-output-hk/haskell.nix/archive/930ec0d277097c7cf2252fc41d9a5e0b9972f1c4.tar.gz
  ) {};
  nixpkgsSrc = haskellNix.sources.nixpkgs-1909;
  nixpkgsArgs = haskellNix.nixpkgsArgs;
  pkgs = import nixpkgsSrc nixpkgsArgs;
in

with pkgs.lib;
with pkgs.haskell-nix.haskellLib;

collectChecks (p:
  p.isLocal && (hasSuffix "systest" p.identifier.name)
) (import ./. {})

See #362

@felixmulder, @zhenyavinogradov, @purefn so this is actually a Cabal bug?

[felixmulder]

Interesting :) Thanks for following up @angerman, with haskell.nix we were actually able to put all tests back into projects next to the library code - so we were able to work around this :)

I think @zhenyavinogradov is right and this was a duplicate of #362. It was recently fixed by #1732.
