kivy: MSVC Install / compile fails on x64 with venv

Versions

• Python: 3.5 x64
• OS: Windows 7 x64
• Kivy: stable 1.9.1; also, master dev branch
• Kivy installation method: MSVC compile instructions here

Description

Attempting to compile/install Kivy fails with linking errors to glew dependencies (stable 1.9.1), or from missing gst/gst.h (1.9.2dev0 master branch). I followed the install docs exactly with one minor difference:

    "C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\vcvarsall.bat" x64

(note the x64 argument; otherwise it fails after trying to build for the wrong architecture target).

At first I thought this might have been related to #4216, but on further investigation it seems unrelated. Modifying path as discussed in docs within #4694 has no effect.

Code and Logs

Building with stable results in the following error:
