class BuildManager:
    """
    统一构建管理：依赖拉取 → CMake 配置 → 并行编译 → 安装 / 测试。

    用法:
        python build.py                  完整构建（拉取依赖 + Release 编译）
        python build.py local            本地构建（跳过依赖拉取，Release 编译）
        python build.py test             单元测试（拉取依赖 + Debug 编译 + 执行测试）
        python build.py test local       单元测试（跳过依赖拉取, Debug 编译 + 执行测试）
        python build.py -r <revision>    指定依赖的内部源码仓(例如msopcom)的 Git 分支/标签/commit

    参数说明:
        - 参数: command : 构建动作: 为空时为全构建, local 为跳过依赖下载, test 为运行单元测试。
        - 参数: -r, --revision : 指定 Git 修订版本或标签用于依赖检出。
