+# 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")

+  # Lib directory for the libraries, as the libraries are in
+  # the Lib directory

+  #
+  # 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.
