编译 opencv 框架时出现未知错误：未定义的符号："_CGImageDestinationCreateWithURL"

Unknown error compiling opencv framework: Undefined symbols: "_CGImageDestinationCreateWithURL"

Xcode给了我以下错误，我真的不知道该怎么办，这让我抓狂。我正在导入一个OpenCV框架，所以可能存在问题或与编译器有关的问题。有人能告诉我该做什么或搜索什么吗？

      Undefined symbols:   "_CGImageDestinationCreateWithURL", referenced from:
      cv::ImageIOEncoder::write(cv::Mat const&, std::vector<int, std::allocator<int> > const&)in OpenCV(grfmt_imageio.o)   "_CGImageDestinationAddImage", referenced from:

为了未来的访客（比如我；-）），我报告了Gustavo的自我回答：

添加"ImageIO.framework"到"链接的框架和库"
