Build keeps failing on linux because "'VULKAN_LAYER_EXPORT' is not a type"

[RustyStriker]

It seems something is a miss, Im running Artix linux(so basically Arch), all packages up to date including FFmpeg, mesa, radeon drivers and such... docs claim i need to install ffmpeg-vulkan but that package is long gone.

added in front is the error i get(well, part of it)

Did you ever resolve this? I too am having the same issue.
