Question

我已经在OSX上安装了OpenCV，如下所示：

(cv1) $ cd ~/opencv
(cv1) $ mkdir build
(cv1) $ cd build
(cv1) $ cmake -D CMAKE_BUILD_TYPE=RELEASE \
    -D CMAKE_INSTALL_PREFIX=/usr/local/include \
    -D PYTHON3_PACKAGES_PATH=~/.virtualenvs/cv1/lib/python3.5/site-packages \
    -D PYTHON3_LIBRARY=/usr/local/Cellar/python3/3.5.0/Frameworks/Python.framework/Versions/3.5/lib/libpython3.5m.dylib \
    -D PYTHON3_INCLUDE_DIR=/usr/local/Cellar/python3/3.5.0/Frameworks/Python.framework/Versions/3.5/include/python3.5m \
    -D INSTALL_C_EXAMPLES=ON \
    -D INSTALL_PYTHON_EXAMPLES=ON \
    -D BUILD_EXAMPLES=ON \
    -D BUILD_opencv_python3=ON \
    -D OPENCV_EXTRA_MODULES_PATH=~/code/opencv_contrib/modules ..
(cv1) $ make -j4 && sudo make install

当我从build内部执行程序时，它们运行正常，但是，当我离开build文件夹时，我收到Symbol not found错误：

(cv1)➜  opencv git:(master) ✗ python ~/code/myprogram.py ~/myimg.jpg
Traceback (most recent call last):

在构建文件夹外运行OpenCV时找不到符号
