To my understanding
- header library: header-only (`.h` files), does not generate object file
- object library: source files (`.cpp` files), generate object files
- entrypoint: similar to object library but it is used to expose symbols to userspace

Here you have a common library that has its own translation units (so object files are generated), and it is used in internal usage, not to expose symbols. So, object library would be proper.
