By default, ExternalLibraries/HDF5 looks for an existing HDF5
installation and performs a few basic tests to see whether this
installation works. It does not check whether compiler versions etc.
match, so it is possible that it finds an incompatible HDF5. To ensure
that the HDF5 library is built, you have to say HDF5_DIR=BUILD.

Should we change this? The only disadvantage of building HDF5 is that
this takes time.
