As VTK is a basis for a number of codes, and is used across quite a
few distros, we tend to be a little more conservative on bumping
requirements. I would ask if HDF5 really needs a newer version, or did
they just bump it to what they had installed at the time?

If there isn't a compelling reason I think we should remain
conservative, and it sounds like there is not in this case (especially
for a dependency that is pretty optional for many of our users). You
can generally always use the latest CMake if you choose, but making
that the minimum makes it harder for others to compile and use our
code (often using the packaged CMake).
