Can a project be build even missing a lib?

There is a Visual Studio project which refers to opencv_world440.lib but it does not seem to be available on vcpkg. I understand vcpkg has opencv 4.3. In order to proceed I tried to remove opencv_world440.lib from VS, project, properties, linker, input, additional dependencies and the project build successfully then. But when I tried to run it return an application error

The application was unable to start correctly (0xc0000017).

I'm not sure what is going on here. May I conclude the project actually does not depend on opencv_world440.lib because it build when I remove it?

Try to use dependency walker to see if it's something related to libraries. Anyway that error code stands for STATUS_NO_MEMORY as described here which indicates a problem with memory (can also be something OS level!?), sorry but I cannot be more specific.

EDIT

"opencv_world" appears to be just one DLL holding all the OpenCV modules, making it easier to distribute. The alternative is to have one library per module. So I guess if you have all the other libraries and it builds, you don't need opencv_world. In few worlds you cannot build a project if you don't have all the necessary libs.
