During May 2025, Mu2ecalo focused on build system configuration within the Mu2e/otsdaq-mu2e repository, specifically modifying the CMake-based build process. They disabled the ROC Tracker Interface by default, altering the CMakeLists.txt to comment out the plugin’s registration. This change streamlined the default build, reducing unnecessary complexity and improving maintainability by limiting the number of enabled features. By leveraging CMake and build system configuration skills, Mu2ecalo ensured that the tracker interface would not be included unless explicitly enabled, which contributed to more stable and predictable builds. The work demonstrated a targeted, thoughtful approach to managing build-time feature selection.
