  24 # FindPacket
  25 # ==========
  26 #
  27 # Find the Packet library and include files.
  28 #
  29 # This module defines the following variables:
  30 #
  31 # PACKET_INCLUDE_DIR     - absolute path to the directory containing Packet32.h.
  32 #
  33 # PACKET_LIBRARY         - relative or absolute path to the Packet library to
  34 #                          link with. An absolute path is will be used if the
  35 #                          Packet library is not located in the compiler's
  36 #                          default search path. See e.g. PACKET_DLL_DIR
  37 #                          variable below.
  38
  39 # PACKET_FOUND           - TRUE if the Packet library *and* header are found.
  40 #
  41 # Hints and Backward Compatibility
  42 # ================================
  43 #
  44 # To tell this module where to look, a user may set the environment variable
  45 # PACKET_DLL_DIR to point cmake to the *root* of a directory with include and
  46 # lib subdirectories for packet.dll (e.g WpdPack/npcap-sdk).
  47 # Alternatively, PACKET_DLL_DIR may also be set from cmake command line or GUI
  48 # (e.g cmake -DPACKET_DLL_DIR=/path/to/packet [...])
  49 #
  50
  51 # The 64-bit Packet.lib is located under /x64
  52 if(CMAKE_SIZEOF_VOID_P EQUAL 8)
  53   #
  54   # For the WinPcap and Npcap SDKs, the Lib subdirectory of the top-level
  55   # directory contains 32-bit libraries; the 64-bit libraries are in the
  56   # Lib/x64 directory.
  57   #
  58   # The only way to *FORCE* CMake to look in the Lib/x64 directory
  59   # without searching in the Lib directory first appears to be to set
  60   # CMAKE_LIBRARY_ARCHITECTURE to "x64".
