Regarding openCV installation dependencies

[zirid]

I installed opencv for windows with cuda using the following cmd :

vcpkg install opencv[cuda,cudnn,dnn,dnn-cuda,ipp,opengl,world]

I am curious whether it is necessary to add additional dll's when opencv installation already generated opencv_world dll ?

My test app can't run without adding all the generated dll's . Is this normal?

Short answer: Yes, you need all those DLLs.

You have built OpenCV and its dependencies as dynamic link libraries, each DLL contains the code for its respective library's functions/classes.

If you'd rather have a single executable, you may look into building your dependencies as static libraries instead.
