修复方法：
sudo dnf install https://download1.rpmfusion.org/ ... usion-free-release-$(rpm -E %fedora).noarch.rpm
sudo dnf install libpng-devel libjpeg-turbo-devel jasper-devel openexr-devel libtiff-devel libwebp-devel libdc1394-devel libv4l-devel gstreamer-plugins-base-devel gtk2-devel tbb-devel eigen3-devel gstreamer1-libav gstreamer1-plugins-base-devel cmake pkg-config swig

还是会报错，但不影响应该。
