On Windows, if we don't find libpcap, look for libwpcap.

Browse Source 
Also, while there may not be a convention for "look for package XXX
here", there is a convention for "look for stuff here" - put "here" in
CMAKE_PREFIX_PATH.  So don't use PCAP_DLL_DIR, just let find_path() and
find_library() search where you tell it (on Windows *or* UN*X).
