Current opencv puts "opencv4.pc" in package config and this breaks mupen64plus-core as it looks for "opencv.pc"; could be your issue, I'm not familiar enough with pkgconfig to know.
(In reply to Todd Walter from comment #2) > Current opencv puts "opencv4.pc" in package config and this breaks > mupen64plus-core as it looks for "opencv.pc"; could be your issue, I'm not > familiar enough with pkgconfig to know. you are right the name of the .pc file must match: ln -s /usr/lib64/pkgconfig/opencv4.pc /usr/lib64/pkgconfig/opencv.pc does the workaround. But it's useless as the source code must be updated to works with OpenCV 4 (>3.4). Build will fail with error like: shotwell-facedetect.cpp:37:22: error: ‘CV_BGR2GRAY’ was not declared in this scope CV_BGR2GRAY must be replace by cv::COLOR_BGR2GRAY , CV_LOAD_IMAGE_COLOR by cv::IMREAD_COLOR .... ( https://www.docs.opencv.org/4.0.0/d8/d01/group__imgproc__color__conversions.html )

Created attachment 687255 [details] Ebuild for shotwell 0.31.3 with support for opencv 4 I've attached a new ebuild for the latest version 0.31.3 which supports opencv 4.

media-gfx/shotwell-0.31.3 compiled successfluly from ebuild https://bugs.gentoo.org/attachment.cgi?id=687255 It works! Face detection works too!
