# Consider using all 6 cores; $ sudo nvpmodel -m 2 or $ sudo nvpmodel -m 0
make -j4

• 安装：

$ git clone https://github.com/jetsonhacks/buildOpenCVTX2.git
$ cd buildOpenCVTX2
$ ./buildOpenCV.sh
$ cd ~/opencv/build
$ sudo make install

• 增加opencv3的库路径 ~/.bashrc

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib/
