Changing Stack's storage directory on Windows

Question

On Windows, Stack uses %AppData/stack as its storage directory by default. Is there a way to change that? I've only managed to move executables (by setting local-bin-path in the global config.yaml file), but I'd like all GHC versions, compiled packages, etc. to be stored somewhere else.

This isn't currently supported, but it should be fairly straightforward to add. I've added a ticket for it here: https://github.com/commercialhaskell/stack/issues/2067

The relevant code is here https://github.com/commercialhaskell/stack/blob/6f7871b893de2792ad9b9a02d934dfa72f8d9090/src/Stack/Config.hs#L266
