Alembic is not a single file format, it can be stored in two different ways: Ogawa and HDF5. Ogawa replaced HDF5 and is smaller and much faster (4-25x) to read ([source](http://exocortex.com/blog/alembic_is_about_to_get_really_fast)). As long as Blender has had Alembic support, it has never supported the HDF5 format in any release. There is a build option `WITH_ALEMBIC_HDF5` that can be used to enable HDF5 support in your own build. This commit removes this build option and the code that it manages. In the years that I have been maintainer of Blender's Alembic code, I only remember getting a request to support HDF5 once, and that was to support very old software that has likely since then been updated to support Ogawa. Ubuntu and Fedora also seem to bundle Blender without HDF5 support. This decision was discussed on [DevTalk](https://devtalk.blender.org/t/alembic-hdf5-support-completely-remove) where someone also mentioned that there is a tool available that can convert HDF5 files to the Ogawa format.
