c++ - 无法通过命令行禁用 OpenCV/MSVC C4265(无虚拟析构函数)错误

Question

我正在尝试在现有项目中使用 OpenCV，但我不断收到此错误消息:

d:\downloads\opencv\build\include\opencv2\core\core.hpp(4903) : error C4265: 'cv::TLSDataContainer' : class has virtual functions, but destructor is not virtual
     instances of this class may not be destructed correctly

我试图通过传递 /wd4265 来禁用错误消息，但它没有帮助!作为引用，下面是完整的命令行。

当我在包含 OpenCV 之前添加 #pragma warning(disable:4265) 时它起作用了!我完全不知道这是从哪里来的。我绝对更愿意在编译脚本而不是代码中禁用此警告。

在 Windows 10 上使用 MSVC 18.00.40418 x64 (vc120)。感谢任何提示。

没关系，我发现 Vendor SDK 将警告变成了错误。

// ge_sys_math.h
#ifdef MAXON_TARGET_WINDOWS
  #pragma warning(disable:4805) // boolean
  #pragma warning(error: 4265)  // non-virtual destructor of virtual classes

  #define __TYPES_READY
#endif

所以我想除了在代码中禁用警告之外，我真的没有别的办法了。
