[netCDF #YMH-767011]: Help with compiling and linking in Windows

Hello,

I don't have a *lot* of experience working with Visual Studio, but I will help 
as best I can.  What you are describing sounds like an error during linking.  
While unfamiliar with the CI tool, it appears you are working with the correct 
file (the .lib import library, not the .dll directly).  You shouldn't need to 
specify -DDLL_NETCDF, nor should you need to modify any files.

What version of Visual Studio are you using, if I may ask? Let me play around 
with my copy of VS and the CI command, and I will follow up with you.  If you 
can tell me what version of VS you are using (to make sure we're on the same 
page), and if you can also confirm you are compiling a 64-bit program, not a 
32-bit program, that will be great. I will follow up as soon as I have more 
information!

Have a great day,

-Ward
