'libgstvulkan-1.0.0.dylib missing from GStreamer plugins bad on OS X/Homebrew

On OS X 12.1, with I'm building an app that is complaining about: dyld[12690]: Library not loaded: @rpath/lib/libgstvulkan-1.0.0.dylib

I've installed the following with Homebrew:

I've been able to find all the required .dylib files so far, except for libgstvulkan-1.0.0.dylib, which should be included with gst-plugins-bad but doesn't appear to be in the Homebrew install.

Questions:

  1. what am I missing? why don't I have libgstvulkan-1.0.0.dylib on my system and where do I get it?
  2. I'd like to know how I can avoid Homebrew and just install the packages directly but I don't see how to get the bad plugins from that side. Do I need to build from source?

My understanding is there is no vulcan dependency in the homebrew formula, thus when building the artifact, there is no libgstvulkan-1.0.0.dylib artifact.

I tried to include molten-vk for the build and turned on vulkan flag, but it has some issue of finding the vulkan_core.h (which is already in /opt/homebrew/Cellar/molten-vk/1.1.8/libexec/include/vulkan/vulkan_core.h).

Local build error:
