正如评论中已经提到的那样，消息

file attempted to write a file ... into a source directory

是在项目的CMakeLists.txt中设置的CMAKE_DISABLE_SOURCE_CHANGES变量的结果。此设置激活检查，即CMake项目不会在源目录下创建任何文件。 (有关此变量设置的更详细说明，请参见该答案。)。

通常，设置CMAKE_DISABLE_SOURCE_CHANGES变量与设置CMAKE_DISABLE_IN_SOURCE_BUILD变量相伴，其字面含义：

该项目不应在源代码中构建。

解决方案是在与源目录不同的build目录中以非源方式构建项目。

例如这样：
