Okay, but if we took this route, which of these would have
PETSC_HAVE_HYPRE? Would it be petscconfksp.h because Hypre is a
preconditioning library? Or petscconfdm.h because KSP depends on DM and
there is some structured grid stuff in Hypre? Both of those answers would
be wrong because of src/vec/vec/impls/hypre/vhyp.c, but I don't see any
good way to locally reason about the link failures that would result from
defining the macro at the wrong level.
