[vtkusers] Building 7.0.0 on 64-bit Windows 10 Python 3.5

[David Gobbi]

Hi Daryl,

The value of WIN32 and _WIN32 should be the same for 64-bit as 32-bit (in
any case, the important thing is whether you're building for a 64-bit vs
32-bit target, not whether you're building on a 64-bit vs 32-bit machine).

I've built VTK with Visual Studio 2015 Update 3 (on Windows 7 Pro 64-bit),
with Python 3.4, but I'm sure that Python is a red herring as far as your
situation is concerned.  Python 3.5 works just fine with VTK.

My suspicion is that your compiler has become mis-configured somehow if it
is spewing a ton of warnings and then dying with an error so early in the
build.  Start with something simple like building a cmake-based "hello
world" program, then try VTK without Python or any other extra options, and
if that works then try building VTK with Python.
