LNK2019 Error, Works fine in cmd, but not visual studio

Question

Hello.
I'm getting this error. I've looked online and it says this happens when something is declared but not defined, however I don't see any issues like that. The most annoying part is that it compiles fine in cmd. I'm not sure why Visual Studio 2013 is giving
me issues

Hi Arend Peter,
Since this forum is to discuss the VS IDE usage, based on your description, it would be the VC++ development issue, to help you resolve this issue as soon as possible, I suggest you post this issue to the VC++ language development forum,
I think you would get dedicated support there.
The VC++ forum link:
