> hvigor WARN: CMake Warning (dev) at CMakeLists.txt:1 (project):

> hvigor WARN: CMake Deprecation Warning at CMakeLists.txt:2 (cmake_minimum_required):
  Compatibility with CMake < 3.5 will be removed from a future version of
  CMake.

  Update the VERSION argument <min> value or use a ...<max> suffix to tell
  CMake that the project does not need compatibility with older versions.

> hvigor WARN: CMake Error at CMakeLists.txt:14 (add_subdirectory):
  add_subdirectory given source
  "C:/Users/admin/DevEcoStudioProjects/MyApplication4/entry/src/main/cpp/../../../oh_modules/@rnoh/react-native-openharmony/src/main/cpp"
  which is not an existing directory.

原因分析：

CMake构建报错是因为add_subdirectory命令指定的源码目录不存在。具体来说，CMakeLists.txt文件的第14行引用了路径C:/Users/admin/DevEcoStudioProjects/MyApplication4/entry/src/main/cpp/…/…/…/oh_modules/@rnoh/react-native-openharmony/src/main/cpp，但这个目录在系统中找不到。

‌主要问题分析：‌

• 1. ‌目录不存在‌：路径oh_modules/@rnoh/react-native-openharmony/src/main/cpp在你的项目中可能没有正确安装或路径配置有误
• 2. ‌路径解析错误‌：使用了相对路径…/…/…/跳转，可能超出了项目根目录范围
     ‌- 3. 依赖模块缺失‌：@rnoh/react-native-openharmony模块可能未安装或安装位置不正确

‌解决思路：‌

• ‌检查目录是否存在‌

手动导航到C:/Users/admin/DevEcoStudioProjects/MyApplication4/oh_modules/@rnoh/react-native-openharmony/src/main/cpp，确认该路径是否真实存在。

-‌ 修复CMakeLists.txt文件‌

如果确认目录不存在，需要修改第14行的add_subdirectory调用

• 确保@rnoh/react-native-openharmony模块已正确安装

或者注释掉该行，如果该依赖不是必需的

• 安装缺失的依赖‌

在项目根目录下运行相应的包管理命令来安装缺失的模块。

• ‌调整CMake命令顺序‌
  还需要调整CMakeLists.txt文件开头的命令顺序

将cmake_minimum_required()移到文件最开头，然后才是project()命令

‌建议操作：‌ 立即检查oh_modules目录下是否存在@rnoh/react-native-openharmony这个包，如果缺失请重新安装依赖。

解决方案：

将以下路径再多加一层，按真实的情况来看，确实已经够了，但是我这里是多加了一层就不报错了。
