C++，OpenCv在C++中虽然构建正确，但却出错

Question

我是C++的新手，但我需要用OpenCV做一个项目。我已经关闭了OpenCv-4.5.2和opencv_contrib，我使用的是Visual 2019。我使用了cmake，没有错误。

然后，在我所包含的项目中，“C:\opencv\opencv_lib\install\include”目录用于我所包含的链接器的C++附加包含目录，“C:\opencv\opencv_lib\install\x64\vc16\lib”用于附加库目录。我在其他依赖项中包含了“opencv_core452.lib,opencv_highgui452.lib,opencv_imgcodecs452.lib”。我为路径添加了“C:...opencv\build\x64\vc14\bin”。

当我运行一个简单的项目时，似乎有些地方出了问题，我不确定是什么。以下是错误：

因为我是新来的，请用简单的语言解释我来解决它。提前感谢！

我终于找到了。我不知道，也许我使用了正确的库和正确的目录，但我决定将所有的库复制到依赖项中，而不仅仅是我使用的那些。下面是我的情况下的所有目录，但请注意，如果您使用的是不同的版本，它们可能是不同的。
