let user enable/disable C++ and Fortran support in ExternalLibraries/HDF5

Issue #457 closed
Roland Haas created an issue

the attached patch exposes two new configuration variables (which default to yes): HDF5_ENABLE_CXX and HDF5_ENABLE_FORTRAN setting them to no allows users to avoid building/linking against the respective interfaces to hdf5. This is useful when eg. one does not need them and would like to link against a cluster supplied version of hdf5 (or if one cannot use the Fortran modules due to differing compiler versions). This kind of relates to Ian's original email: http://lists.einsteintoolkit.org/pipermail/users/2011-March/000928.html Although it does not provide any early warning.

    Approved.

    I would put the new code that deals with these new variables into its own section (delimited by #, as in the script) instead of attaching it to "prepare" and "search", which doesn't quite fit.

    turns out seem to be unable to commit the patch (hdf5_enable_cxx_fortran2.diff above) since the repository lives in cactuscode.org.
