vulkan: macOS dev static library is not universal

Describe your issue

I was linking against gst-vulkan-1.0 as provided by the 1.22.5 dev package, on an macOS universal app (-DCMAKE_OSX_ARCHITECTURES:STRING=x86_64;arm64).

Expected Behavior

Linking should succeed.

Observed Behavior

CMake Tools reported the following warning on final linking:

[build] ld: warning: ignoring file /Library/Frameworks/GStreamer.framework/Versions/1.0/lib/libgstvulkan-1.0.a, file is universal (x86_64) but does not contain the arm64 architecture: /Library/Frameworks/GStreamer.framework/Versions/1.0/lib/libgstvulkan-1.0.a

Setup

  • Operating System: macOS 12.7.5
  • Device: Computer
  • GStreamer Version: 1.22.5
  • Command line: N/A

Steps to reproduce the bug

I can simplify testing this to:

  1. open terminal
  2. type file /Library/Frameworks/GStreamer.framework/Versions/1.0/lib/libgstvulkan-1.0.a
  3. compare with the output of file /Library/Frameworks/GStreamer.framework/Versions/1.0/lib/libgstreamer-1.0.a

How reproducible is the bug?

Always. The framework seems to be improperly packaged just for that one plugin.
