cerbero.errors.FatalError: Fatal Error: The required packaging tool 'WiX' was not found

[Ben Rush]

Two things, really.

I'm trying to get essentially a build similar to what I'd get if I
downloaded the MSVC 64-bit (VS 2019) build from here:
https://gstreamer.freedesktop.org/download/. I'm a little concerned I'm
still building simply the mingw binaries. I'm essentially doing the
following (from Windows):

./cerbero-uninstalled -c config/win64.cbc bootstrap

and then

./cerbero-uninstalled -c config/win64.cbc package gstreamer-1.0

But I'm seeing files named "libgstwebrtc.dll", etc. under
"cerbero\build\sources\mingw_x86_64" instead of
"cerbero\build\sources\windows_x86_64" which I would assume to be the
location for the Visual Studio-built binaries. I'm taking instructions from
https://gstreamer.freedesktop.org/documentation/installing/building-from-source-using-cerbero.html?gi-language=c
 and
https://www.cardinalpeak.com/build-gstreamer-on-windows-an-advanced-tutorial/
.

In addition, I've installed Wix per the instructions laid out here:
https://gstreamer.freedesktop.org/documentation/installing/building-from-source-using-cerbero.html?gi-language=c,
but I'm getting the following error right at the end of the build process
(any thoughts on debugging this? I'm so close...). I really, really want to
get a build environment going here for Windows that'll produce the Visual
Studio-produced binaries we use in our product so I can start testing some
changes, etc.
