The helper function ~trexio_has_backend~ returns ~true~ if TREXIO compilation includes a back end provided as an argument; ~false~ otherwise.
The helper function ~trexio_has_back_end~ returns ~true~ if TREXIO compilation includes a back end provided as an argument; ~false~ otherwise.
This is useful due to the fact that HDF5 back end can be disabled at configure step.
