Apple macOS and MoltenVK
------------------------
Zink on macOS is experimental with very limited capabilities.
The Vulkan SDK (1.3.250 or newer) is required to build Zink.
Set the build option ``-Dmoltenvk-dir=<directory>`` to point at your Vulkan SDK install or MoltenVK build.
Add Zink to the Gallium drivers build option ``-Dgallium-drivers=zink``.
If installed using ``brew``, you can set ``-D moltenvk-dir=$(brew --prefix molten-vk)``.
