Andrey Labazov enhanced the build system for the facebookresearch/faiss repository by introducing a configurable CMake option, FAISS_ENABLE_EXTRAS, to improve embeddability and integration flexibility. This feature allows users to selectively compile extra components such as benchmarks and demos, which are now optional when FAISS is used as a subproject. By defaulting the option to ON, Andrey ensured backward compatibility and avoided regressions for existing users. The work focused on build system configuration using C++ and CMake, reducing the build footprint and simplifying downstream integration. The depth of the change addressed both usability and maintainability for diverse project requirements.
