[Haskell-cafe] external git dependency source in .cabal

[Vanessa McHale]

In your .cabal file, yes, but the cabal.project file can reference
external packages. It has a slightly different syntax, though.

I don't think it's supported with cabal-install 2.0.0.1. You may have to
use HEAD instead of 2.4.0.0, I don't know.
