[netCDF #OEJ-560742]: configure error

The z library (usually called zlib) is a popular and widely used library for 
lossless compression, which is already included with many Unix systems, 
but can also be downloaded and installed from various package management
systems (for example dpkg, yum, homebrew, macports, anaconda, ...) or built 
from source (see http://www.zlib.net/). 

NetCDF-4 depends on an HDF5 library that is built with zlib enabled, so
zlib must be built and installed before HDF5, which must be built and
installed before netCDF-4.  The package management systems mentioned
above will do this for you, but if you need to build the libraries on which
GMT depends from source for some reason, see these instructions for 
building the netCDF-C library with zlib and hdf5:

If you are having trouble building HDF5 with zlib, please consult the HDF5
installation instructions:
