Interesting, thanks for the report! glslValidator is supposed to be provided by glsl_to_spirv crate. It looks for it in the build folder at run-time (which is annoying to package...). I've been running it on many many systems and haven't seen this happening.

I get the same error on my project here https://github.com/MatusT/vis2-molecules.

thread 'main' panicked at 'Failed to execute glslangValidator: Os { code: 2, kind: NotFound, message: "The system cannot find the file specified." }', C:\Users\matus\.cargo\registry\src\github.com-1ecc6299db9ec823\glsl-to-spirv-0.1.7\src\lib.rs:53:18

Seems like wgpu-rs hardcodes path to glsl-to-spirv? I guess this should be moved to wgpu(-rs)/glsl_tospirv issues.

@MatusT it's not wgpu-rs. It doesn't depend or include glsl-to-spirv in any way.
