These steps have been tested for Ubuntu 10.04 but should work with other distros as well.
包括树莓派b3，ubuntu，亲测完全可用
1.sudo apt-get install build-essential
2.sudo apt-get install cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev
3.sudo apt-get install python-dev python-numpy libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libjasper-dev libdc1394-22-dev
