Handle spaces for Python install location in MSVC scripts

michaelpq · michaelpq · commit 984aca448d5d · 2020-05-06T21:08:26.000+09:00
Attempting to use an installation path of Python that includes spaces caused the MSVC builds to fail. This fixes the issue by using the same quoting method as ad7595b for OpenSSL.
