Subject: [PATCH] Fixes https://github.com/zeromq/cppzmq/issues/361, by
 incorperating Ferdnyc's changes in OpenShot/libopenshot, previously cppzmq
 was not looking for the correct names, and rejected valid static library
 names when looking for zmq on windows, this fix aims to include those other
 names
