OpenCV - DLL missing, but it's not?

Question

I am trying just a basic program with OpenCV with the following code:

#include \"cv.h\"
#include \"highgui.h\"

int main()
{
    IplImage* newImg;
    newImg

This might be like resurrecting a dead horse. But just so it's out there, the reason why the answer to these types of questions to simply put dll's into the system32 folder is because that folder is in the os's system path.

It's actually best practice to provide the os with a path link.

With windows 10

1. open up file explorer
2. right click on "this pc" and select "properties"
3. Now in the "Control Panel\System and Security\System" window that comes up, click on "Advanced System Settings" from the left hand panel.
4. At the bottom of the next window, click on the "Environment Variables" button.
5. On the next window, there are two panels, the top one is for modifying variables to the current user, and the bottom panel is for modifying variables to the system. On the bottom panel, find the variable "Path" and click it to select it, then click on the "edit" button.
6. Here you can then create, edit, delete, or update the different paths for the system. For example, to add mingw32-make to the system so you can access that command via command prompt, click new, then paste in the path to the bin. Example path, "D:\Qt\Tools\mingw730_64\bin", no quotation marks nor additional whitespaces.
7. Click ok on all the windows so that the changes are saved, then reboot your computer for the changes to be loaded.
