During December 2025, this developer contributed to the microsoft/vcpkg repository by updating the FastDDS port to version 3.4.1, focusing on improving dependency management and ensuring compatibility with required libraries. Using C++ and CMake, the work targeted stability and interoperability for downstream components, reducing integration risks and supporting smoother release cycles. The technical approach involved aligning FastDDS with the necessary library versions, which enhanced build reliability across dependent projects. The update was completed and merged collaboratively, with clear traceability in the project’s history. This contribution demonstrates a methodical approach to dependency compatibility and build system maintenance within C++ ecosystems.
