[netCDF #EGO-288225]: Cannot link to hdf5.

The info we were missing was the hdf5 options you used to build hdf5.
The relevant errors from the config.log are these:
> configure:16955: mpicc -o conftest -I/home/pf4d/local/hdf5-1.10.2/include > 
> -I/home/pf4d/local/hdf5-1.10.2/include -L/home/pf4d/local/hdf5-1.10.2/lib > 
> -lhdf5 -lhdf5_hl conftest.c -lhdf5  -lm -lz  >&5
> /usr/bin/x86_64-linux-gnu-ld: warning: libsz.so.2, needed by 
> /home/pf4/local/hdf5-1.10.2/lib/libhdf5.so, not found (try using -rpath or 
> -rpath link)
> /home/pf4d/local/hdf5-1.10.2/lib/libhdf5.so: undefined reference to 
> `SZ_encoder_enabled'
>/home/pf4d/local/hdf5-1.10.2/lib/libhdf5.so: undefined reference to 
>`SZ_BufftoBuffCompress'
They indicate that
1. libz was not found; you may need to specify its location both
   when compiling hdf5 and when compiling netcdf
2. It appears that hdf5 was compiled with szlib support turned on but
   szlib was not found when compiling netcdf.
