Following the Getting Started guide running the first example fails

cargo run --release --example draw

Fails with:

cargo:rerun-if-changed=build/glslangValidator.exe looks suspicious since I am on macOS
Also glsl-to-spirv appears to be a deprecated dependency.

Any ideas how to get anything running?

Interestingly enough, generative_design and nature_of_code examples run out of the box.

After some deeper investigation seems like there issue is with the hotglsl dependency.

Despite there being a few newer commits, the dependency is locked at 1c1a303, which is before replacing glsl-to-spirv with naga.

Regenerating Cargo.lock and patching nannou_isf/src/pipeline.rs seems to solve the issue for me.

I see now this is already addressed by #988

[Boscop]

I'm also affected by this.
@mitchmindtree Can you please merge the PR #988 ? :)
