Although you say the build went fine, something likely went wrong with either the build or install. I would suggest saving the output of the build and posting it here....

hopefully someone with some knowledge of building and installing python C extensions with C lib dependencies on windows will chime in - I have no clue. Curious why installing via...

@kmuehlbauer other than via copy and paste, I don't know of any way to do that.

@kmuehlbauer sorry but the option to transfer an issue to Unidata/netcdf-c is not available for me.

Please try running ncdump on the file - this will tell us if it's an issue with the C library or the python interface. Also, you might check the file...
