Howdy Matt!
For zstandard, and other filter features, you must build and use shared
libraries.
Also you need to build netcdf-c with --with-plugins=/some/path and then set
environment variable HDF5_PLUGIN_PATH to /some/path before you build
netcdf-fortran (or use any program with the zstandard filter).
