How to configure netcdf in cygwin. While configuring netcdf the following error occur-

configure: error: Can't find or link to the z library. Turn off netCDF-4 and opendap with --disable-netcdf-4 --disable-dap, or see config.log for errors.

i am using cdo

$ cdo -v
OpenMP: num_procs=4 max_threads=1 num_devices=0

No operator given!

usage : cdo [Options] Operator1 [-Operator2 [-OperatorN]]

    -h, --help     Help information for the operators
    --history      Do not append to NetCDF "history" global attribute
    --netcdf_hdr_pad, --hdr_pad, --header_pad <nbr>
                   Pad NetCDF output header with nbr bytes
    -k <chunktype> NetCDF4 chunk type: auto, grid or lines
    -L             Lock IO (sequential access)
    -M             Switch to indicate that the I/O streams have missing values
    -m <missval>   Set the missing value of non NetCDF files (default: -9e+33)
    --no_warnings  Inhibit warning messages
    -O             Overwrite existing output file, if checked
    --operators    List of all operators
    -P <nthreads>  Set number of OpenMP threads
    --percentile <method>
                   Percentile method: nrank, nist, numpy, numpy_lower, numpy_higher, numpy_nearest

                   Precision to use in displaying floating-point data (default: 7,15)
    --reduce_dim   Reduce NetCDF dimensions
    -R, --regular  Convert GRIB1 data from reduced to regular grid (cgribex only)
    -r             Generate a relative time axis
    -S             Create an extra output stream for the module TIMSTAT. This stream
                   contains the number of non missing values for each output period.
    -s, --silent   Silent mode
    --sortname     Alphanumeric sorting of NetCDF parameter names
    -t <codetab>   Set GRIB1 default parameter code table name or file (cgribex only)
