After upgrading opencv to 4.1.2 and rebuilding digikam (implicitly and explicitly using emerge @preseved-rebuild), digikam can't find opencv while configuring itself: -- liblcms found............................ YES -- libopencv found.......................... NO CMake Error at core/cmake/modules/MacroUtils.cmake:46 (message): libopencv is needed. You need to install the libopencv (version >= 3.1.0) development package. Call Stack (most recent call first): core/CMakeLists.txt:581 (PRINT_LIBRARY_STATUS) Reproducible: Always
i ran into the same thing, seems to be because of this bug in opencv-4: https://bugs.gentoo.org/701472
#701472 is fixed. Please test again and reopen, if the bug is still there.
