C++ Visual Studio release build is not working (OpenCV 4.5.2)

Now, I tried to build release mode from C++ source code with OpenCV.

This source code is built on debug mode, but it is not built on release mode.

The below images are my OpenCV library setting.

Please give me your help

The error is most probably happening because you provided OpenCV library named ...d.lib to your release linker configuration.

d suffix in library file name means that it is debug library. All .lib files are usually shipped as two files, one for release (without d) and one for debug (with d).

Try to find release .lib and place it into your linker configuration.
