Worked on stabilizing the ExaTrkX plugin integration within the andiwand/acts repository by addressing a critical build system issue. Focused on C++ development and CMake configuration, the work involved correcting the linkage of std::filesystem to resolve conflicts when building the plugin with Athena. By changing the linkage from public to private in CMakeLists.txt, the update eliminated build-time crashes and runtime failures, improving reliability across different environments. The solution reduced CI/CD pipeline downtime and streamlined onboarding for future integration efforts. Documentation of the change and its rationale was provided to support ongoing maintenance and prevent similar regressions in the future.
