 准备完三方库代码后，我们需要将三方库加入到编译构建体系中。标准系统编译构建可以参考文档[编译构建指导](https://gitee.com/openharmony/docs/blob/OpenHarmony-3.2-Beta4/zh-cn/device-dev/subsystems/subsys-build-all.md)。  <br />
 我们默认三方库是属于OpenHarmony的thirdparty子系统，如果需要自己定义子系统参考文档[如何为三方库组件中添加一个三方库](https://gitee.com/openharmony-sig/knowledge/blob/master/docs/openharmony_getstarted/port_thirdparty/README.md)。<br />
