[Haskell-cafe] Using a library in a executable within same cabal package

[Arnaud Bailly]

Hello,
Not sure this question is totally on-topic. Please point me in the right
direction if it is not. I would like to make a cabal package containing
both an executable and several libraries, and link the main executable
to the libraries produced in the build. It is not clear how I can
achieve that from the documentation. I tried Extra-libraries option but
it does not work.

Thanks for your help
