我正试图通过终端在Ubuntu上为Python安装一个人脸跟踪器。我从这里安装：
https://pypi.python.org/pypi/pyFaceTracker/0.1.1
并从这里使用了setup.py的linux版本：http://reidmayo.com/2014/07/15/how-to-install-pyfacetracker-on-linux-fedora-19/
但是，当我试图在包的目录中键入"sudo python setup.py install"时，它最终给了我这个错误：

如果有帮助的话，我会为C++使用OpenCV 3.0.0 alpha，为python使用OpenCV 3.0 beta。
我该怎么解决这样的问题？
要让它找到cv:：remap，正如@berak所说，你必须让它包括opencv2/opencv.hpp，但不包括在_pyFaceTracker.cpp中，你必须把它包括在这里（IO.h）。IO.h在PAW.h中使用，并实现cv:：remap函数。完成这些操作后，我消除了那个错误，并偶然发现了另一个关于helper函数的错误。有什么想法吗？
警告：前方有很长的路要走！`
