This package will work with netcdf3 or netcdf4.

netcdf >= 4.1 should have a utility 'nc-config'.  This is looked for
on the path or where specified by the --with-nc-config configure
argument or NC_CONFIG environment variable, and if found is used to
set PKG_CPPFLAGS and PKG_LIBS.  Occasionally this is unreliable, and
can be skipped by setting either the argument or the environment
variable to a non-existent path

If no valid 'nc-config' utility is found, the rest of this file applies.

The location of the netcdf header can be specified by the environment
variable NETCDF_INCLUDE or the configure argument
--with-netcdf-include, e.g. Fedora 12 needed
--with-netcdf-include=/usr/include/netcdf3
and Solaris' native compilers needs
--with-netcdf-include=/usr/local/include

The location of the netcdf library can be specified by the environment
variable NETCDF_LIB or the configure argument --with-netcdf-lib.

netcdf <= 4.0.1 is normally self-contained, but netcdf >= 4.1.0 is
usually linked against HDF5.  Environment variable HDF5_LIB or
configure argument --with-hdf5-lib can be used to specify the path to
the HDF5 libraries.

The configure script looks to link against first
-lnetcdf
and if that fails
-lnetcdf -lhdf5 -lhdf5_hl -lcurl -lz
The latter is what is usually required for a static build of netcdf
4.1.x, but provision is made to specify another set of additional
libraries via environment variable NETCDF_EXTRAS or configure argument
--with-netcdf-extra-libs.
