The settings are predefined, so only a few, like “os” or “compiler”, are possible. They are defined in your ~/.conan/settings.yml file. Also, the possible values they can take are restricted in the same file. This is done to ensure matching naming and spelling between users, and settings that commonly make sense to most users. Anyway, you can add/remove/modify those settings and their possible values in the settings.yml file, according to your needs, just be sure to share changes with colleagues or consumers of your packages.

If you want to distribute a unified settings.yml file you can use the conan config install command.


The settings.yml file is not perfect nor definitive, surely incomplete. Please send us any suggestion (or better a PR) with settings and values that could make sense for other users.
