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 # The 64-bit Packet.lib is located under /x64
51 if(CMAKE_SIZEOF_VOID_P EQUAL 8)
52 #
53 # For the WinPcap and Npcap SDKs, the Lib subdirectory of the top-level
54 # directory contains 32-bit libraries; the 64-bit libraries are in the
55 # Lib/x64 directory.
56 #
57 # The only way to *FORCE* CMake to look in the Lib/x64 directory
58 # without searching in the Lib directory first appears to be to set
59 # CMAKE_LIBRARY_ARCHITECTURE to "x64".
