enhancement: Enhance Makefile for better build process and fix errors

- Removed unnecessary `ls` command in the `cpp-static-lib` target
- Reorganized build targets for clarity and proper execution order
- Ensured that the build directory (`build-cpp`) is created before use
- Fixed issues with missing source files and library paths in the `cpp-static-lib` target
- Remove `println` statement: test_list_authorized_users
