Question

环境：MacOS 10.12，CMake 3.9.0，python 2.7

我尝试使用此tutorial在mac上编译Opencv当我按照步骤8

时

$ cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local \
    -D PYTHON2_PACKAGES_PATH=~/.virtualenvs/cv/lib/python2.7/site-packages \
    -D PYTHON2_LIBRARY=/usr/local/Cellar/python/2.7.10/Frameworks/Python.framework/Versions/2.7/bin \
    -D PYTHON2_INCLUDE_DIR=/usr/local/Frameworks/Python.framework/Headers \
    -D INSTALL_C_EXAMPLES=ON -D INSTALL_PYTHON_EXAMPLES=ON \
    -D BUILD_EXAMPLES=ON \
    -D OPENCV_EXTRA_MODULES_PATH=~/opencv_contrib/modules ..

$ make -j4

我收到了以下信息

/Users/niceycb/opencv/modules/videoio/src/cap_qtkit.mm:46:9: fatal error: 
      'QTKit/QTKit.h' file not found
#import <QTKit/QTKit.h>

第一个错误是已知问题（因为在OS X v10.9中不推荐使用QuickTime Kit，我的MacBook版本：10.12）并且我已经遵循了几个解决方案，但没有一个工作。

我不知道第二个错误，似乎没有解决方案。

在MacOS10.12上编译opencv时“找不到符号”
