  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.
  37
  38 # Packet_FOUND           - TRUE if the Packet library *and* header are found.
  39 #
  40 # Hints and Backward Compatibility
  41 # ================================
  42 #
  43 # To tell this module where to look, a user may set the environment variable
  44 # Packet_ROOT to point cmake to the *root* of a directory with include and
  45 # lib subdirectories for packet.dll (e.g WpdPack or npcap-sdk).
  46 # Alternatively, Packet_ROOT may also be set from cmake command line or GUI
  47 # (e.g cmake -DPacket_ROOT=C:\path\to\packet [...])
  48 #
  49
  50 if(CMAKE_GENERATOR_PLATFORM STREQUAL "Win32")
  51   #
  52   # 32-bit x86; no need to look in subdirectories of the SDK's
  53   # Lib directory for the libraries, as the libraries are in
  54   # the Lib directory
  55   #
  56 else()
  57   #
  58   # Platform other than 32-bit x86.
  59   #
  60   # For the WinPcap and Npcap SDKs, the Lib subdirectory of the top-level
  61   # directory contains 32-bit x86 libraries; the libraries for other
  62   # platforms are in subdirectories of the Lib directory whose names
  63   # are the names of the supported platforms.
  64   #
  65   # The only way to *FORCE* CMake to look in the appropriate
  66   # subdirectory of Lib for libraries without searching in the
  67   # Lib directory first appears to be to set
  68   # CMAKE_LIBRARY_ARCHITECTURE to the name of the subdirectory.
