 - On Ubuntu with oneAPI compilers, `CMake` HDF5 installations are supported (`apt` versions only support `gfortran`).
 
 :::{note}
 Codes using HDF5 built with `oneAPI` compilers should not have the `-standard-semantics` flag: it changes module name mangling from `_mp_` to `_MP_` which makes HDF5 modules unavailable.

+The `netcdf` metapackage will automatically link against the NetCDF Fortran and C libraries.
+It exposes the `netcdf` module for Fortran90, `netcdf_f03` and `netcdf4_f03` for
+Fortran 2003, as well as the underlying lower-level modules. Similar to HDF5, `fpm`
+uses `pkg-config` to find a valid local NetCDF installation.
