This repository uses subtrees to manage some of its externals. ## Initial setup ``` git remote add externals-fmt https://github.com/fmtlib/fmt.git git remote add externals-xbyak https://github.com/herumi/xbyak.git ``` ## Updating Change `` to refer to the appropriate git reference. ``` git fetch externals-fmt git fetch externals-xbyak git subtree pull --squash --prefix=externals/fmt externals-fmt git subtree pull --squash --prefix=externals/xbyak externals-xbyak ```
