Ubuntu下查看linux版本
pkg-config --modversion opencv
sudo apt-get install build-essential libgtk2.0-dev libvtk5-dev libjpeg-dev libtiff4-dev libjasper-dev libopenexr-dev libtbb-dev
下载好opencv3.2(https://opencv.org/releases.html)后，将源码解压.
mkdir build && cd build
输入命令
cmake -D CMAKE_BUILD_TYPE=RELEASE -D WITH_TBB=ON -D WITH_V4L=ON -D CMAKE_INSTALL_PREFIX=/usr/local/opencv320 ..
make
sudo make install
紧接着需要配置下文件，通过修改bashrc文件来设置PKG_ CONFIG_PATH（后来发现好像还需要改一下LD_LIBRARY_PATH）
sudo gedit ~/.bashrc
export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/opencv320/lib/pkgconfig
export LD_LIBRARY_PATH=$PKG_CONFIG_PATH:/usr/local/opencv320/lib
