# -D CMAKE_INSTALL_PREFIX=/usr/local/opencv4，则默认各部分分别安装在/usr/local/include/；/usr/local/bin；/usr/local//lib/3个文件夹下
cmake -D CMAKE_BUILD_TYPE=Release -D OPENCV_GENERATE_PKGCONFIG=YES ..
make -j8
sudo make install

opencv环境配置
- pkg-config配置
  - sudo find /usr/local -name opencv4.pc
  - sudo vim /etc/profile.d/pkgconfig.sh
  - export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:$PKG_CONFIG_PATH（这里假设路径是/usr/local/opencv4/lib/pkgconfig）
  - source /etc/profile
  - 验证是否成功：pkg-config --libs opencv4
    - -L/usr/local/opencv4/lib -lopencv_ml -lopencv_dnn -lopencv_video -lopencv_stitching -lopencv_objdetect -lopencv_calib3d -lopencv_features2d -lopencv_highgui -lopencv_videoio -lopencv_imgcodecs -lopencv_flann -lopencv_photo -lopencv_gapi -lopencv_imgproc -lopencv_core
- 动态库环境配置
  - sudo vim /etc/ld.so.conf.d/opencv4.conf
  - 在文件中加入：/usr/local/opencv4/lib
  - sudo ldconfig
