Detailed description

When trying to compile OpenCV 4.8.1 with opencv_contrib repository, the compilation fails due to the module Xphoto :

Steps to reproduce

Inside OpenCV-4.8.1 repository directory : 
rm -rf build
mkdir build
cd build 
cmake .. -DOPENCV_EXTRA_MODULES_PATH=<path_to_opencv_contrib_dir>/modules
make -j <number_of_cores>

You need to keep both opencv / opencv_contrib repositories synchronized (same tag / version / commit date). Different versions may not work.

Build / usage questions should go to Users OpenCV Q/A forum: https://forum.opencv.org/

Ok, I have checkout on the 4.8.1 tag in the contrib repo and it works. Thanks !
