      # Since the HDF5 ADIOS2 VOL connector is part of the ADIOS2 repository,
      # it is difficult to use CMake's FetchContent functionality to fetch
      # and build the ADIOS2 connector. Also, since building of ADIOS2 takes
      # a while, it isn't ideal to have to rebuild it every time we want to
      # test against changes in HDF5 or the VOL connector. Therefore, just
      # use a fixed commit for the build of ADIOS2 so we can cache that and
      # still test the connector against changes in HDF5.
