Worked on stabilizing the build system for the KhronosGroup/Vulkan-ValidationLayers repository, focusing on improving reliability for macOS development environments. Addressed a persistent build inconsistency by ensuring that the CMAKE_OSX_SYSROOT variable was correctly propagated to all dependency builds, aligning them with the host SDK path. This approach reduced intermittent failures in continuous integration and improved reproducibility across Apple platforms. Leveraged expertise in build engineering, CMake, and macOS development to enhance cross-platform build hygiene, ensuring that dependencies compiled consistently within the Vulkan Validation Layers suite. The work centered on bug resolution, with no new features introduced during the documented period.
