Error compiling and running example `runners/ash`

Expected Behaviour

Example runners/ash compiles and runs.

Example & Steps To Reproduce

1. git clone https://github.com/Rust-GPU/rust-gpu
2. cd rust-gpu/yard-rs/example-xp/rust-gpu/examples/runners/ash
3. cargo run --release
4. error:

thread 'main' panicked at examples/runners/ash/src/main.rs:255:10:
called `Result::unwrap()` on an `Err` value: CratePathDoesntExist("examples/shaders/sky-shader")

Following the working example multibuilder, one can change the error line from

SpirvBuilder::new("examples/shaders/sky-shader", "spirv-unknown-vulkan1.1")

to

SpirvBuilder::new(concat!(env!("CARGO_MANIFEST_DIR"), "/../../shaders/sky-shader"), "spirv-unknown-vulkan1.1")

Now the example and the shader crate compiles, but running it gives an error

[mvk-error] VK_ERROR_EXTENSION_NOT_PRESENT: Vulkan extension VK_KHR_shader_non_semantic_info is not supported.
thread 'main' panicked at examples/runners/ash/src/main.rs:441:22:
called `Result::unwrap()` on an `Err` value: ERROR_EXTENSION_NOT_PRESENT

This might be fixable by updating ash, or might not be fixable at the moment. In the latter case, an explicit "support matrix"-ish table would be nice.

Backtrace

N/A

<backtrace>

Start by running cargo run --release in examples/runners/ash and inspect examples/runners/ash/src/main.rs around lines 255 and 441. Compare its shader path handling with the working multibuilder example and investigate the reported VK_KHR_shader_non_semantic_info failure on macOS. Done means the example runs, or its unsupported requirements are documented in an explicit support matrix.
