Common Package Specification (CPS) in Practice: Working Implementation in Conan C++ Package Manager
Talkat CppCon 2024 · on Monday, 2024-09-16· at 14:00· Spruce 3/4, 6700 North Gaylord Rockies Boulevard·
summary
A working CPS implementation lands inside Conan and actually generates tens of thousands of packages (and the metadata for half a million binaries) from ConanCenter; the repo ships a CPS deps generator (available in Conan 2.7) that emits CPS files and maps them back to Conan, then generates CMake, Meson, Autotools and MSBuild files so an example app is built across four build systems successfully while revealing gaps (missing install-time headers, component relationships, CPS file resolution).
