No, I don't think that's very practical at the moment. At the moment I'd
just keep it in one .cabal file and just add all the src dirs and .c
files etc that you need into each program section. It's not very pretty
but it's not completely unwieldy.

What we should probably do is make it easier to deal with a collection
of packages including registering packages in-place and then it'd become
quite practical to have multiple .cabal files, one for each lib and
binary in your system. And you'd be able to express the proper
dependencies between them.

This is the kind of thing that people have been thinking about for a
while, but there are some tricky issues and it's also quite a lot of
work.

Nothing easy.
