WSL Opencv with_ffmpeg conan1.60.0

我是ubuntu18.

self.options[“OpenCV”].with_FFmpeg = True
关键是GCc版本需要conan支持，比如我的是：
compiler=gcc
compiler.version=7.5

此外还需要安装系统所需库：

甚至来说，可以装一些系统编译好的，免得没有系统文件：

sudo apt-get install build-essentialsudo apt install ffmpeg --fix-missingsudo apt-get install pkg-configsudo apt install libopencv-dev
