On FreeBSD, one must actually link against libpcap (or give the path to a shared object at link time). That is, it is not a header-only library on that platform. Account for this by adding a new boolean variable in `platform-quirks.cmake`: `NEED_PCAP_LIBRARY`, which defaults to false. Condition pcap library discovery and link argument modifications on that variable in `FindPCAP.cmake` and `dep-link.cmake`.
