 ### 编写CMakeLists.txt
 
-基于上一步生成的`headers|libs`，用户可以使用`CMakeLists`等工具引入该依赖；在`CMakeLists`中，可以通过向`CMAKE_CXX_FLAGS`添加`-I|L`分别指定`headers|libs`路径；然后使用`add_library`添加动态库。例如，在`be/src/udf_samples/CMakeLists.txt`中，使用`add_library(udfsample SHARED udf_sample.cpp)`增加了一个`udfsample`动态库。后面需要写上涉及的所有源文件（不包含头文件）。

 ### Edit CMakeLists.txt
 
-Based on the `headers | libs` generated in the previous step, users can introduce the dependency using tools such as `CMakeLists`; in `CMakeLists`, dynamic libraries can be added by adding `-I|L` to `CMAKE_CXX_FLAGS`, respectively. For example, in `be/src/udf_samples/CMakeLists.txt`, a `udf sample` dynamic library is added using `add_library` (udfsample SHARED udf_sample.cpp). You need to write down all the source files involved later (no header files included).
