| # Rebuilds the shaders needed for the GPU cube test. |
| # For SPIR-V: requires glslangValidator and spirv-cross, which can be obtained from the LunarG Vulkan SDK. |
| # For DXBC compilation: requires FXC, which is part of the Windows SDK. |
| # For DXIL compilation, requires DXC, which can be obtained via the Windows SDK or via here: https://github.com/microsoft/DirectXShaderCompiler/releases |
| # For Metal compilation: requires Xcode |
| |
| # On Windows, run this via Git Bash. |
| # To add the Windows SDK (FXC/DXC) to your path, run the command: |
| # `export PATH=$PATH:/c/Program\ Files\ \(x86\)/Windows\ Kits/10/bin/x.x.x.x/x64/` |
