        The netCDF-4 configuration depends on the netCDF-4 and HDF5 installation!
	You have to define the location of the HDF5 installation if netCDF-4 was 
        build with HDF5 support:

        You have to specify also the location of the SZLIB if HDF5 was build with 
        SZLIB support.

        To process szip compressed GRIB files you have to enable SZLIB support with:
          --with-szlib=<directory>

     2. Do "make" to compile the program.

     3. (Optional) Do "make install", possibly as root if the destination
        permissions require that. This installs CDO in the directory
        specified during configuration. The default prefix is /usr/local.

Porting:

     This package was designed for maximum portability. It is written entirely
     in ANSI C99, and will compile on most UNIX platforms.
