oh, this has been answered soo often here ..

first, this is no error. it's a warning. the prebuilt opencv libs indeed come without pdb files (dl size).

so, you can still run / debug your own code , but you can't dive into the opencv libs while debugging.

again, no error. if you still need that feature, you'll have to rebuild opencv locally using cmake, this will generate those pdb files, too.
