[Josh Grebler]

Describe the bug

To Reproduce
Follow build instructions for Python Release

Expected behavior
No warnings are expected
Build folder is expected at dhart/build/Python/

Screenshots
The following output is produced by the first step:

Additional context

Some of the Visual Studio tools required in BUILD.md are not listed in the Visual Studio Community 2019 Installer by name. As many as could be found + anything related was used.
