Cabal: N executables without building all the modules N times?

[Niklas Hambüchen]

Hey James,

yes, if you want to avoid duplicate compilation, you need to define a `library` with a separate `hs-source-dirs` and use that library in the `build-depends` of your executables.

See

and the linked question.

Cheers,
