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
52if(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".
