# 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         - relative or absolute path to the Packet library to
#                          link with. An absolute path is will be used if the
#                          Packet library is not located in the compiler's
#                          default search path.

# Packet_FOUND           - TRUE if the Packet library *and* header are found.
#
# Hints and Backward Compatibility
# ================================
#
# To tell this module where to look, a user may set the environment variable
# Packet_ROOT to point cmake to the *root* of a directory with include and
# lib subdirectories for packet.dll (e.g WpdPack or npcap-sdk).
# Alternatively, Packet_ROOT may also be set from cmake command line or GUI
# (e.g cmake -DPacket_ROOT=C:\path\to\packet [...])
#

if(CMAKE_GENERATOR_PLATFORM STREQUAL "Win32")
  #
  # 32-bit x86; no need to look in subdirectories of the SDK's
  # Lib directory for the libraries, as the libraries are in
  # the Lib directory
  #
else()
  #
  # Platform other than 32-bit x86.
  #
  # For the WinPcap and Npcap SDKs, the Lib subdirectory of the top-level
  # directory contains 32-bit x86 libraries; the libraries for other
  # platforms are in subdirectories of the Lib directory whose names
  # are the names of the supported platforms.
  #
  # The only way to *FORCE* CMake to look in the appropriate
  # subdirectory of Lib for libraries without searching in the
  # Lib directory first appears to be to set
  # CMAKE_LIBRARY_ARCHITECTURE to the name of the subdirectory.
  #
