Worked on enhancing the build system for the Autodesk/hydra-viewport-toolbox repository by refactoring the CMakeLists.txt to improve reliability and clarity for contributors. The approach involved using CMake scripting to conditionally locate the pxr package only if it was not already defined, and updating CTest initialization to ensure it runs only when the project is at the top level. These changes reduced unnecessary CI and test failures, streamlined iteration cycles, and made onboarding easier for new developers. The work demonstrated a strong understanding of build system design, dependency management, and test framework integration within a CMake-based development environment.
