### AMD FSR2 SDK (External)
- Build scripts (`build.sh`, `rebuild.sh`, `build.ps1`, `rebuild.ps1`) auto-fetch the AMD SDK to:
- `extern/FidelityFX-FSR2`
- Source URL:
- `https://github.com/GPUOpen-Effects/FidelityFX-FSR2.git`
- The renderer enables the AMD backend only when both are present:
- `extern/FidelityFX-FSR2/src/ffx-fsr2-api/ffx_fsr2.h`
- `extern/FidelityFX-FSR2/src/ffx-fsr2-api/vk/shaders/ffx_fsr2_accumulate_pass_permutations.h`
- If SDK files or generated Vulkan permutation headers are missing, CMake falls back to the internal non-AMD FSR2 path automatically.
