H A Dcmake转gn指导文档.md188 假设我们有一个简单的CMake项目，包含两个源文件：main.cpp和hello.cpp，以及一个头文件hello.h。CMakeLists.txt文件内容如下：
192 project(hello)
194 add_executable(hello main.cpp hello.cpp hello.h)
199 hello/
201 │ └── hello.h
203 ├── hello.cpp
208 1. 在OpenHarmony代码中，增加example目录，将hello示例放在example目录下，在hello目录下新建BUILD.gn文件，示例如下：
219 part_name = "hello"
227 part_name = "hello"
263 "base_group": [ "//example/hello:hello" ],
