Hi folks,

I am following the steps at this website:

https://www.wireshark.org/docs/wsdg_html_chunked/ChSetupWin32.html

and I get this error:

c:\Users\blah-blah\Wireshark>nmake -f Makefile.nmake verify_tools

Microsoft (R) Program Maintenance Utility Version 12.00.21005.1
Copyright (C) Microsoft Corporation.  All rights reserved.

Makefile.nmake(8) : fatal error U1052: file 'win32.mak' not found
Stop.

These appear to be in the environment:

CYGWIN=nodosfilewarning
QT5_BASE_DIR=C:\Qt\5.4\msvc2013_64_opengl
VisualStudioVersion=12.0
WIRESHARK_BASE_DIR=c:\Users\rjsharpe\Wireshark
WIRESHARK_TARGET_PLATFORM=win64
WIRESHARK_VERSION_EXTRA=-RJS

What else do I need to do?
