Month: 2025-08 — Cross-repo open-source build readiness for proxygen::coro via c-ares integration across four Facebook repos. Added c-ares manifests and migrated to the official CMake package (find_package(c-ares)) to replace the legacy FindCares.cmake, enabling open-source builds, improving build reliability, and accelerating release readiness. Key commits include: in facebookincubator/cinderx: add manifest for c-ares (30998b58...), use find_package(c-ares) (1f3c615e...); in facebook/CacheLib: add manifest for c-ares (e85dfeec...), use find_package(c-ares) (67c49921...); in facebook/fboss: add manifest for c-ares (da5027ea...), use find_package(c-ares) (619cded7...); in facebook/fbthrift: add manifest for c-ares (cc159887...), use find_package(c-ares) (3593b6b0...). These changes standardize dependency management across repos, reduce external build friction, and speed up releases. Technologies demonstrated include CMake modernization, manifest-based dependency management, and cross-repo collaboration. Business value includes faster time-to-market, broader contributor base, and more reliable build systems.
