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 51if(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". 60 # 61 # In newer versions of CMake, CMAKE_LIBRARY_ARCHITECTURE is set according to 62 # the language, e.g., CMAKE_<LANG>_LIBRARY_ARCHITECTURE.
