Can I get Stack to use my revised Cabal library?

Question

Does anyone know if there is an easy way to make Stack use a specific patched version of the Cabal library from my GitHub repository? I am very pleased with how I can use forked versions of other packages by simply placing them in the packages: stack.yaml , but this does not seem to work with Cabal.

I would like to specify the way the git repository url and version in stack.yaml and have a Cabal library built from this source and not from Hackage or any other upstream repository. It can be done?

Stack will use the latest version of the Cabal library in your global database, so you need to install it (for example, using the Setup.hs script).
