[netCDF #QWR-165524]: building netcdf-c failed with error "ld: unknown option: --no-undefined"

Hello,

This failure should not be a problem; it is one of the test programs used by 
`cmake` to determine the capabilities of the system, and the output you provide 
looks as one would expect if the linker does not support the `--no-undefined` 
flag. 

Does cmake itself indicate an error when configuring netCDF, or does make 
generate an error when trying to compile?  If so, can you provide the errors 
you see on the command line?  

Thank you,

-Ward
