Hi

i am trying the script to build opencv on windows from here : https://docs.opencv.org/master/d3/d52... with cuda, perf tests, tests and documentation enabled. But i get below error for multiple projects. LINK : fatal error LNK1104: cannot open file '....\lib\Debug\opencv_img_hash440d.lib'

i have both opencv and opencv_contrib scyned properly. I always used this cript and it used to work properly.

opencv_img_hash440d.lib. Are you building for debug? Try release.

It happens with both release and debug builds.
