根因分析

CMakeLists.txt调用了一个未定义的函数或宏，原因是缺少include、拼写错误或不支持的模块。

English

A CMakeLists.txt calls a function or macro that is not defined, due to a missing include, typo, or unsupported module.

解决方案

  1. 检查拼写错误：确保命令拼写正确（例如'target_link_libraries'而不是'target_link_library'）。
  2. 如果命令来自自定义模块，在调用前添加include(MyModule)，或使用include(path/to/module.cmake)。
  3. 如果命令来自旧版CMake，升级CMake或使用兼容性包装：cmake_minimum_required(VERSION 3.10)。

无效尝试

常见但无效的做法:

  1. Typing the command name in a different case (e.g., 'My_Function' vs 'my_function') 30% 失败

    CMake commands are case-insensitive but must match exactly; case issues rarely cause this error.

  2. Adding the command as a comment to suppress the error 100% 失败

    Comments are ignored; the command must be defined or removed.

  3. Installing a third-party module without including it 80% 失败

    The module must be included with include() or find_package() before use.
