Opencv_world.dll on windows

Q1.
I write a foo library that use opencv. When I use the foo, my program will show can not found opencv_world.dll.

I dont want to depend on the opencv_world.dll. How can I do?

Why? If you build a static version of OpenCV it will be the same size as including opencv_world.dll with your application so there will be no difference apart from the number of files you include. i.e. One large application file or one smaller application file and one opencv_world.dll.

Q2.
main project bar will call the foo
where foo is a library and it use the opencv.

Does it mean when I use the foo libraray, I must be put opencv_world.dll on my main project (same folder)

This was answered in your previous post

Why need to set the path for opencv_world4100d.dll

opencv_world4100d.dll not found I download pre-compiled opencv. And using the opencv in my project on windows It always show “opencv_world4100d.dll not found” Until I set the variable to windows env by hand. Q1. Why need to set opencv_world4100d.dll ? Becuase other lib just find_package(XXX) And then I can directly use. Q2. Does any method (automatically) to set the path for windows? Not the interface operation.

To clarify you can

1. Include in your project directory
2. Add to the the location to your system/user path
3. Build a static version of OpenCV and link against that but you need to clarify why you would want to do that and why option 1 and 2 are not suitable solutions for you?
