I'd argue that fixing the CMakeLists also falls into snippet territory,
as it's directly related to unbundling.

Could this be done with substitute* as for the other packages?  If not,
we should group those options under a sufficiently explanatory comment.
Also, there's little need to explicitly enable things that would
already be enabled by default, let's keep the list of flags small and
understandable :)

When you send v3, please do all patches in one go and also specify --
reroll-count, as that's easier on mumi.

Thanks
