根因分析

add_executable() 或 add_library() 中列出的源文件在磁盘上不存在。常见原因：文件被移动、重命名、删除，或路径相对于错误的目录。

English

The source file listed in add_executable() or add_library() does not exist on disk. Common causes: file was moved, renamed, deleted, or the path is relative to a wrong directory.

解决方案

  1. 验证文件是否存在于确切路径。使用绝对路径或从 CMAKE_CURRENT_SOURCE_DIR 开始的正确相对路径。示例：
  set(MY_SRC ${CMAKE_CURRENT_SOURCE_DIR}/src/module.cpp)
  add_executable(myapp ${MY_SRC})
  2. 如果文件已被移动，更新 CMakeLists.txt 指向新位置。修复后运行 'cmake --build . --clean-first'。
  3. 如果使用生成的文件，确保在定义目标之前生成它们。使用带 OUTPUT 的 add_custom_command，并将输出添加到目标的源文件中。

无效尝试

常见但无效的做法:

  1. 60% 失败

    The stale CMake cache may still reference the old path, causing the same error. A full reconfigure is needed.

  2. 90% 失败

    The error is about a missing source file, not about target existence. Adding to another target doesn't create the missing file.

  3. 75% 失败

    If the file doesn't exist on disk, no extension change will help. The file must be present and the path must match exactly.
