git clone https://github.com/opencv/opencv.git

cd opencv

mkdir build

mkdir install

cd build

cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/path/to/opencv/install ..
(這裡可以根據需求加入參數 -D xxx)

make -j7

make install

使用範例:

g++ -Wall main.cpp -I/path/to/opencv/install/include -L/path/to/opencv/install/lib -ldl -lm -lpthread -lopencv_core -lopencv_imgproc -lopencv_highgui -lopencv_objdetect
