DFetch can manage dependencies

We make products that can last 15+ years; because of this we want to be able to have all sources available to build the entire project from source without depending on external resources. For this, we needed a dependency manager that was flexible enough to retrieve dependencies as plain text from various sources. svn externals, git submodules and git subtrees solve a similar problem, but not in a VCS-agnostic way or completely user-friendly way. We want self-contained code repositories without any hassle for end-users. Dfetch must promote upstreaming changes, but allow for local customizations. The problem is described thoroughly in managing external dependencies and sometimes is also known as vendoring.

Other tools that do similar things are Zephyr's West, CMake ExternalProject and other meta tools. See alternatives for a complete list.
