     Type:  defect                  |      Status:  new                
 Priority:  minor                   |   Milestone:                     
Component:  EinsteinToolkit thorn   |     Version:  development version
 Keywords:  SphericalHarmonicRecon  |  
------------------------------------+---------------------------------------
 SphericalHarmonicRecon's Recon.cc file uses H5LTread_dataset_double
 (https://support.hdfgroup.org/HDF5/doc/HL/RM_H5LT.html#H5LTread_dataset_double)
 which is only available in the hdf5 hl level library which is only
 provided in hdf5 1.8.7.

 Nothing in the ET states that HDF5 1.8 is required.

 This can be fixed my making sure that hdf5_hl is included in HDF5_LIBS
 which also will make compilation fail if the library in indeed missing.

 We should decide whether we want to bump ExternalLibraries/HDF5's version
 number and have it itself check for HDF5 1.8 in which case thorns can rely
 on this version being present (if they require a new enough HDF5
 ExternalLibraries) or provide workarounds in Reconn.cc.
