summary
Conan describes a concrete, implemented Common Package Specification used by +1500 open source Conan packages and by thousands of teams, producing roughly 500,000 binary packages and millions of downloads; the spec serializes package contents (json/yaml), maps to CMake MSBuild Meson Autotools, expresses include/lib dirs as relative paths, models components and build‑vs‑package views, records compiler flags and runtime env, and surfaces real problems (cross‑build protoc, conditional builds, merging components) along with lessons that do and do not scale.
