使用opencv_contib安装OpenCV 3.2时未指定"OPENCV_TEST_DATA_PATH环境变量"

我正在尝试在Ubuntu 16.04上安装OpenCV 3.2和opencv_contrib中的模块.

但是,当我运行该sudo make install命令时,我得到以下输出:

事情是,我正在非常努力的时候运行相同的错误make -j8命令,然后我添加的OPENCV_TEST_DATA_PATH环境变量,我~/.bashrc和~/.zshrc文件是这样的:

export OPENCV_TEST_DATA_PATH=/home/denis/code/opencv_extra/testdata

我事先已经下载了opencv_extra repo.错误消失了!我可以成功运行make -j8命令.

运行该make -j8命令后,我尝试运行该sudo make install命令并获得您在上面看到的输出.

指定了此环境变量:

?  build echo $OPENCV_TEST_DATA_PATH
/home/denis/code/opencv_extra/testdata

所以,我不太清楚我该怎么做才能正确安装OpenCV.

PS:这是cmake我使用的命令:

cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D WITH_TBB=ON -D BUILD_NEW_PYTHON_SUPPORT=ON -D WITH_V4L=ON -D INSTALL_C_EXAMPLES=ON -D INSTALL_PYTHON_EXAMPLES=ON -D BUILD_EXAMPLES=ON -D WITH_QT=ON -D WITH_OPENGL=ON -D WITH_CUBLAS=ON -D OPENCV_EXTRA_MODULES_PATH=../../opencv_contrib/modules ..

你能帮我解决这个问题吗？
