Just to follow up on the above replies, you could also just build a single package. For example, you could build asynchronous_union_find with `bazel build //in_memory/connected_components:asynchronous_union_find`. (This isn't very useful outside of the context of a cc_binary rule.)

This in turn allows you to only build and use the 'package' you care about without having to build the whole repo in other projects. Continuing on the above example, if you only wanted to use the asynchronous_union_find.h header file in your project, somewhere in your WORKSPACE file, you add the graph-mining library using a git_repository rule (see WORKSPACE.bazel for examples), and in a cc_library rule in a BUILD file inside your project, you can add a `@graph-mining//in_memory/connected_components:asynchronous_union_find`. Then you can include it as a header elsewhere. Building your project then only builds that package and its dependencies, and not the entire graph-mining library.
