Comment (by rhaas):

 I believe that with Debian/Ubuntu and their multi-arch features the
 replacement
 {{{
 HDF5_LIB_DIRS="${HDF5_DIR}/lib"
 }}}
 can no longer be used and instead one has to use
 {{{
 HDF5_LIB_DIRS="${HDF5_DIR}/$(gcc -dumpmachine)/lib"
 }}}
 (see
 https://trac.einsteintoolkit.org/attachment/ticket/1769/hdf5_dumpmachine.patch)
 which of course assumes that (a) gcc exists and (b) will break on "normal"
 non-multiarch OS (ie OSX and older or non-Debian based Linux).

 It ''may'' be useful to still check that the given directory exists and/or
 that libhdf5 is found in there. Otherwise the linker will silently fall
 back to a possibly existing system HDF5 library. This is strictly and
 ''extra'' though since the current code certainly does not do so.
