How to install OpenCv 3.1.0 without root permissions ?

Question

I downloaded the OpenCv 3.1.0 package and I would like to install it on Ubuntu 16.04. I am not sudo on my computer and I wanted to know how to install correctly OpenCV locally.

You can install OpenCV to any folder that you have write permission with CMAKE_INSTALL_PREFIX flag, whose default is /usr/local. For example:

mkdir build && cd build
cmake -D CMAKE_INSTALL_PREFIX='/home/username/local' ..
make -j8 && make install

Since header files and libraries are not install in system path, you have to configure your OpenCV projects manually.
