[vtkusers] VtK 7, python3.4 build error

[David Gobbi]

Hi Matthew,

I downloaded the latest python 3.5 package from python.org this morning and
did a test build of VTK against it.  There weren't any problems with the
build (I tried with both cmake-2.8 and cmake-3.4, both of them worked).  It
found the following include dir and library:

PYTHON_INCLUDE_DIR:PATH=/Library/Frameworks/Python.framework/Versions/3.5/include/python3.5m
PYTHON_LIBRARY:FILEPATH=/Library/Frameworks/Python.framework/Versions/3.5/lib/libpython3.5m.dylib

Please let me know if you discover anything new.

 - David
