media-libs/opencv-4.1.2 doesn't install a pkgconfig file /usr/lib64/pkgconfig/opencv.pc and breaks a lot of other packages because of that.
Confirmed, same problem here.
opencv deprecated pkgconfig support from version 4.0.0 on... https://github.com/opencv/opencv/issues/13154 for newer versions it needs special flags set to install it, see here: https://github.com/opencv/opencv/blob/master/doc/tutorials/introduction/linux_install/linux_install.markdown quote: --- Add this flag when running CMake: `-DOPENCV_GENERATE_PKGCONFIG=ON` Will generate the .pc file for pkg-config and install it. Useful if not using CMake in projects that use OpenCV Installed as `opencv4`, usage: `pkg-config --cflags --libs opencv4` ---
Created attachment 598004 [details] updated ebuild to install pkg-config file
