CCAN (C Code Archive Network) http://ccodearchive.net/ http://ccodearchive.net/ follows a similar philosophy. CCAN contains various small, self contained snippet of C code are meant to be be downloaded in a local directory ("vendored") and used directly or with small modifications. The most straightforward way to use CCAN is to 1) `git clone` it in a subdir; 2) create a `config.h`; 3) include whatever `lib.h` you want in your project. Updating these micro dependencies means doing `git pull`. All libraries come with tests and a somewhat standardized API design. What is missing (compared to your aims) is a declarative way to lock a dependency to a specific version.
