【opencv基础】OpenCV installation stuck at [ 98%] Built target opencv_perf_stitching with no error

前言

按照官网步骤安装opencv的过程中进行到98%时一直没有继续进行。

原因

后台一直在编译运行，只需等待即可，参考here；

well, turns out it gets stuck for quite a long time and then moves forward successfully. Don't stop the installation. BE PATIENT!

bash
