Conan vs MELPA

Conan is a free, open-source package manager for C and C++ projects. It manages dependencies and binary packages through Conan recipes, with dependency resolution, lockfiles, workspaces, private registry authentication and offline installation. Binary configurations can vary by architecture, compiler and version, runtime, and C++ standard library. If a matching binary is unavailable, Conan can build from source on demand. It supports Windows, Linux, macOS, Android, iOS, embedded and bare-metal targets, as well as desktop, server and mobile platforms. Build integrations include CMake, MSBuild, Makefiles, Meson and SCons; other integrations include Docker, MinGW, WSL and JFrog Artifactory. Teams can share and reuse native binaries. Artifactory Community Edition offers self-hosted private package hosting, with a WebUI, authentication and permissions. Conan is released under the MIT License. The listed plan describes the package manager as free and open source; no price is stated for either plan.
