VSG_ALPHA_TEST and vsgshadows example

[avilkinnick]

Hi, I copied VSG example "vsgshadows" and trying to load my gltf model through this, it is loading without extra arguments, but when I add argument "--at" to add alpha channel to textures, such error is shown:

Warning: GLSL source failed to parse.
Warning: glslang info log:

I have just checked vsgshadow --at with the default model and gltf models and it's running cleanly for me. I'm using VSG, vsgXchange and vsgExample master on Kubuntu 24.04.

What version of VSG, vsgXchange and vsgExamples are you using? Is the VSG built with glslang support?

Thanks, I just needed new shaders from vsgExamples
