1.下载VS2015
2.下载CMake 3.12.0
3.下载Dlib:
Dlib官网地址:http://www.dlib.net/ml.html
官网下载最新dlib文件
解压放在F盘，并新建一个文件build
用cmake—gui搞了一个下午，一直编译不过，最后改成官网推荐的命令行编译了。
右键shirt打开cmd，操作：
-
cd build
-
cmake -G "Visual Studio 14 2015 Win64" ..
-
巴拉巴拉之后，再输入
cmake --build . --config Release
Release X64位比较快，Debug比较慢，在VS2015配置编译也只是Release X64下
巴拉巴拉之后，这时候在F:\dlib-19.15\build\dlib\Release下有
dlib_lib.lib是我新建备份的
注：选择SSE4或者AVX是官网说在release下，可以加快编译速度，如：http://dlib.net/faq.html#Whyisdlibslow
VS2015新建一个空的win32，C++项目
打开view>>other windows>>项目管理器
编译源码时，需要添加一个源文件source.cpp，使用添加现有项的方式。
目录是F:/dlib-19.15/dlib/all/source.cpp
全部改为自己的目录路径既可以
再添加main文件

点击编译即可
按照上面就不会出现
USER_ERROR__inconsistent_build_configuration__see_dlib_faq_2和
USER_ERROR__inconsistent_build_configuration__see_dlib_faq_1
的问题，但是
（1）如果遇到png.h文件找不到，确定附加库目录已经包含dlib，使用"dlib/external/libpng/png.h"去代替<png.h>即可。
（2）最好使用Release版本去编译使用，速度快。
（3）如在Debug模式下OBJ字节数组太大，则在属性 -> C/C++ -> 命令行 加入/bigobj即可。
（4）若读取jpeg图片错误或找不到jpeglib.h，在第五步中，加入DLIB_JPEG_STATIC即可。
（5）如果是使用VS2015，主要要更新到update 3,这才支持C++11的
