【问题描述】：
我想使用 Dlib 进行面部标志检测，并尝试将其安装在我的 macOS Sierra 上。我按照main GitHub Repo for dlib 中的说明进行操作。
进入示例文件夹后，我首先执行了以下操作，没有错误：
mkdir build; cd build; cmake .. ; cmake --build .
恢复到父目录，我执行了以下操作：
sudo python2.7 setup.py install
这在完成 38% 后遇到了 20+ 个错误：

[ 35%] Building CXX object dlib_build/CMakeFiles/dlib.dir/stack_trace.cpp.o

稍微研究了一下，我觉得有一条小路径（到 python）我需要更改才能让一切正常工作。参考a similar problem，他更改了 CMakeCache.txt 中的一些路径，但我不确定是哪一行/部分。此外，还有 4 个 CMakeCache.txt 文件。我应该更改哪一项（如果有）？
Ajays-MacBook-Pro:dlib Ajay$ find . -name "CMakeCache.txt"
./examples/build/CMakeCache.txt
./examples/build/cpp11_test_build/CMakeCache.txt
./tools/python/build/CMakeCache.txt
./tools/python/build/cpp11_test_build/CMakeCache.txt
还有其他解决方案吗？我该怎么办？任何帮助将不胜感激！
