    # - Try to find libpcap include dirs and libraries

    # Usage of this module as follows:
    #
    #     find_package(PCAP)
    #
    # Variables used by this module, they can change the default behaviour and need
    # to be set before calling find_package:
    #
    #  PCAP_ROOT_DIR             Set this variable to the root installation of
    #                            libpcap if the module has problems finding the
    #                            proper installation path.
    #
    # Variables defined by this module:
    #
    #  PCAP_FOUND                System has libpcap, include and library dirs found
    #  PCAP_INCLUDE_DIR          The libpcap include directories.
    #  PCAP_LIBRARY              The libpcap library (possibly includes a thread
    #                            library e.g. required by pf_ring's libpcap)
    #  HAVE_PF_RING              If a found version of libpcap supports PF_RING
