  # FindPacket
  # ==========
  #
  # Find the Packet library and include files.
  #
  # This module defines the following variables:
  #
  # PACKET_INCLUDE_DIR     - absolute path to the directory containing Packet32.h.
  #
  # PACKET_LIBRARY         - relative or absolute path to the Packet library to
  #                          link with. An absolute path is will be used if the
  #                          Packet library is not located in the compiler's
  #                          default search path. See e.g. PACKET_DLL_DIR
  #                          variable below.
  
  # PACKET_FOUND           - TRUE if the Packet library *and* header are found.
  #
  # Hints and Backward Compatibility
  # ================================
  #
  # To tell this module where to look, a user may set the environment variable
  # PACKET_DLL_DIR to point cmake to the *root* of a directory with include and
  # lib subdirectories for packet.dll (e.g WpdPack/npcap-sdk).
  # Alternatively, PACKET_DLL_DIR may also be set from cmake command line or GUI
  # (e.g cmake -DPACKET_DLL_DIR=/path/to/packet [...])
  #
  
  # The 64-bit Packet.lib is located under /x64
  set(64BIT_SUBDIR "")
  if(CMAKE_SIZEOF_VOID_P EQUAL 8)
    set(64BIT_SUBDIR "/x64")
  endif()
  
  # Find the header
