This is an effort to be able to use the same GLSL code for both Vulkan and OpenGL. This is done by first compiling the Vulkan GLSL code to SPIR-V and then using a custom tool (which uses SPIRV-Cross) to convert that back into GLSL 1.50 compatible code. The required tool will be downloaded by CMake when glslc is found in the path. This is included in the Vulkan SDK. To avoid having a hard dependency on this, the generated files are included in the VCS and are only regenerated when glslc is found on the system.
