How to have multiple build flavors with stack?

When developing, I want to build everything with -O0 to save time.

But when building the same package on a CI system, I want to use -O.

One option I see would be to have two different stack.yaml files differing in their ghc-options, but then I'd have to make all changes to stack.yaml in two places.

Having an alias for stack --ghc-options=-O0 doesn't work, because I want -O0 to apply only to local packages, not the snapshot, and there's no way to specify that on the command line, from what I know.

Are there any better options?

Actually, stack build --ghc-options=-O0 will apply -O0 to only the local packages, not to the snapshot packages. For more information, see:
