In your ~/.cabal/config file (translate the path to Windows, I've no idea
where the config goes there), there's a field for that, set
And from then on cabal (install) passes the -split-objs flag (or was that
--split-objs?) to GHC when installing packages. You'd have to rebuild the
packages you already have.

It's something the user decides, not the package author.
