I made a minor fix. Please use latest Vulkan SDK and the master branch.

Trying to build on macOS with latest Vulkan SDK, zstd and KTX-Software installed, but still getting this error:

Any ideas?

Finally found a way to build it on macOS. Had to replace the libzstd.a from KTX-Software (in glTF-IBL-Sampler/thirdparty/KTX-Software/other_lib/mac/Release/) with one from zstd installed with homebrew.
