# FindPacket
# ==========
#
# Find the Packet library and include files.
#
# This module defines the following variables:
#
# PACKET_INCLUDE_DIR - absolute path to the directory containing Packet32.h.
# PACKET_LIBRARY - absolute path to the Packet library to link with.
# PACKET_FOUND - true if the Packet library *and* its headers are found.
#
# Hints and Backward Compatibility
# ================================
#
# To tell this module where to look, a user may set the environment variable
# PACKET_DLL_DIR to point cmake to the *root* of a directory with include and lib
# subdirectories for packet.dll (e.g WpdPack/npcap-sdk).
# Alternatively, PACKET_DLL_DIR may also be set from cmake command line or GUI
# (e.g cmake -DPACKET_DLL_DIR=/path/to/packet [...])
#
if(NOT PACKET_DLL_DIR)
set(PACKET_DLL_DIR $ENV{PACKET_DLL_DIR})
endif()
# The 64-bit Packet.lib is located under /x64
set(64BIT_SUBDIR "")
if(CMAKE_SIZEOF_VOID_P EQUAL 8)
set(64BIT_SUBDIR "/x64")
endif()
# Find the header

# else()
# message(FATAL_ERROR "Could not find Packet32.h. See README.Win32 for more information.")
