simple-static on Windows 10 - ZeroMQ requires ws2_32 and Iphlpapi about simple HOT 4 CLOSED

Oh wait! Are you using libzmq 4.2.3 (I'm guessing from the name of the lib files)?
simple required ZeroMQ 4.2.4+!

from simple.

That is very strange, since the CI runs for VS15 as well. And I also never experienced that on Windows 10.
Do you maybe use Windows 10 32-bit? Also that "ws2_32" suggests it.

from simple.

Everything is 64-bit. I'm using Windows SDK 10.0.16299.0. Without ws2_32 and Iphlpapi, I get link errors such as:

2>libzmq-v141-mt-s-4_2_3.lib(zmq.obj) : error LNK2019: unresolved external symbol __WSAFDIsSet referenced in function zmq_poll
2>libzmq-v141-mt-s-4_2_3.lib(socket_poller.obj) : error LNK2001: unresolved external symbol __WSAFDIsSet
2>libzmq-v141-mt-s-4_2_3.lib(select.obj) : error LNK2001: unresolved external symbol __WSAFDIsSet

Ah! Yes I was. Thanks for catching that!
