This may be a long-standing nit of mine with Windows Wireshark development
environments.

Unless you really have a need, e.g. for other work on the same machine,
then do NOT put Cygwin on your path, it has in the past caused all kinds of
issues.  Both nmake and CMake have mechanisms to locate Cygwin as required.

If you must have Cygwin on the path for other tasks, then you may be better
off creating a VM for your Wireshark work that doesn't put Cygwin on the
path.  This is the method I've used for a number of years as it allows me
to isolate and control the Wireshark build env on machines that are
normally used for building other software as part of the day job.

A further bump along this path :-), is Git.  You must make sure you install
Git without the option "Use Git and optional Unix tools from the Windows
Command Prompt" as this then interferes with CMake finding the Cygwin tools
we want.

For Python, I have both the Windows native Python directory (e.g.
C:\Python27) and the Python scripts directory (e.g. C:\Python27\Scripts) on
my path, the latter for git-review.
