注意本教程配置环境：win7 32位
如果只配置vs2013+opencv2.4.11，参考
【具体步骤】
一、准备配置
下载并安装vs2013
下载并安装Qt5.5.1
下载并安装opencv2.4.11
下载qt-vs-addin-opensource-1.2.5
二、开始配置
1、 安装qt-vs-addin-opensource-1.2.5。安装成功后vs2013的菜单栏上会多出一个Qt5的选项
2、 选择QT5-&Qt Options，将Qt下msvc2013的路径添加进来
3、 将opencv\build\x86\vc12\bin文件添加到系统环境变量中
选中系统变量中的Path点击编辑将opencv的安装目录下的bin文件路径添加到环境变量中。我的目录是D:\StudyProgram\OpenCV2_4_11\opencv\build\x86\vc12\bin
(注意: 添加完环境变量之后需要重启电脑才能生效。)
下面进行一次性永久配置
新建一个C++|Win32控制台应用程序项目
视图|其他窗口|属性管理器
在debug上右键，选择添加新项目属性表，命名为opencv2411_debug
双击opencv2411_debug，设置属性。
属性页面中C/C++-&常规，选择附加包含目录添加Qt下的Include文件路径，我的是D:\StudyProgram\QT5_5_1\5.5\msvc2013\include
4.添加Opencv和Qt的库文件具体操作如下：
选择VC++目录添加可执行文件目录、包含目录、库目录
（注意：opencv库文件最好选择x86使用x64版本在编译时可能会提示错误。vs2012对应VC11，vs2010对应vc10，vs2013对应vc12。）
可执行文件: D:\StudyProgram\OpenCV2_4_11\opencv\build\x86\vc12\bin
& &包含目录: D:\StudyProgram\ OpenCV2_4_11\opencv\build\include
&&&&&&&&&& &D:\StudyProgram\OpenCV2_4_11\opencv\build\include\opencv
&&&&&&&&&& &D:\StudyProgram\OpenCV2_4_11\opencv\build\include\opencv2
& &库目录:
D:\StudyProgram\OpenCV2_4_11\opencv\build\x86\vc12\lib
&&&&&&&&&&&&&&&&&&&&&&& D:\StudyProgram\QT5_5_1\5.5\msvc2013\lib
5.选择链接器-&输入|附加依赖项。注意，后面加d的是Debug版本的文件没加d的是Release版本的文件。
Debug版本文件：（复制粘贴如下内容即可）
qtmaind.lib
Qt5Cored.lib
Qt5Guid.lib
Qt5Widgetsd.lib
Qt5Sqld.lib
opencv_ml2411d.lib

如何确定VS编译器版本
_MSC_VER是MSVC编译器的内置宏，定义了编译器的版本，_MSC_VER 值对应版本关系
MSVC++ 11.0 _MSC_VER = 1700 (Visual Studio 2012)&
MSVC++ 10.0 _MSC_VER = 1600 (Visual Studio 2010)
MSVC++ 9.0 _MSC_VER = 1500& (Visual Studio 2008)&
MSVC++ 8.0 _MSC_VER = 1400& (Visual Studio 2005)&
MSVC++ 7.1 _MSC_VER = 1310& (Visual Studio 2003)
MSVC++ 7.0 _MSC_VER = 1300 (Visual Studio 2002)
MSVC++ 6.0 _MSC_VER = 1200&
MSVC++ 5.0 _MSC_VER = 1100
#if (_MSC_VER == 1300)& //vc7
#import &acax16ENU.tlb& no_implementation raw_interfaces_only named_guids
#elif (_MSC_VER == 1200)& //vc6
#import &acad.tlb& no_implementation raw_interfaces_only named_guids
#elif (_MSC_VER == 1400) //vc8
#import &acax17ENU.tlb& no_implementation raw_interfaces_only named_guids
#elif (_MSC_VER == 1500) //vc9
#import &acax18ENU.tlb& no_implementation raw_interfaces_only named_guids
在程序中加入_MSC_VER宏可以根据编译器版本让编译器选择性地编译一段程序。例如一个版本编译器产生的lib文件可能不能被另一个版
本的编译器调用，那么在开发应用程序的时候，在该程序的lib调用库中放入多个版本编译器产生的lib文件。在程序中加入_MSC_VER宏
，编译器就能够在调用的时根据其版本自动选择可以链接的lib库版本，如下所示。
#if _MSC_VER &= 1400 // for vc8, or vc9
#ifdef _DEBUG
#pragma comment( lib, &SomeLib-vc8-d.lib& )
#pragma comment( lib, &SomeLib-vc8-r.lib& )
#else if _MSC_VER &= 1310 // for vc71
#ifdef _DEBUG
#pragma comment( lib, &SomeLib-vc71-d.lib& )
#pragma comment( lib, &SomeLib-vc71-r.lib& )
#else if _MSC_VER &=1200 // for vc6
#ifdef _DEBUG
#pragma comment( lib, &SomeLib-vc6-d.lib& )
#pragma comment( lib, &SomeLib-vc6-r.lib& )

博主最近用vlfeat库做课题，网上搜索使用方法，一大片都会告诉你说：run(/vl_setup) 然后就好啦哈哈哈哈哈哈~~~~~~~~~~~~~~
But!理想很丰满，现实很骨感，当博主在官网下载了vlfeat并按照如下操作之后：
MATLAB却出现了如下错误：
Invalid MEX-file 'D:\codingtool\library\vlfeat\toolbox\mex\mexw64\vl_version.mexw64': 找不到指定的模块
我就知道没这么简单啊摔(╯‵□′)╯︵┻━┻问题的关键是我进入mex\mexw64\明明能找到这个模块的！为什么MATLAB不可以！你是有多笨！！（博主的工科男票竟然让博主重新解压再来一次操作就好了呢~~博主考虑要不要换个男票了= =）于是博主痛定思痛，准备用vs先编译一下vlfeat再看看效果，没想到意外的成功了！好嗨森·~~下面就是完整的流程啦~
Step 1 准备工作要做好~
准备好vs2012(其他版本也可以，只要保证与MATLAB里的一致就好)、vlfeat包http://www.vlfeat.org/index.html、MATLAB R2014b(其他版本应该也可以了啦~)
Step 2 &VS2012编译vlfeat
1. &打开VS2012 x64 Native Tools Command Prompt，在命令行中依次输入如下图所示的命令：
看到上面的版本号11.00.50727.1了木有宝宝们？记住它哈~
2. &在vlfeat/make/nmake_helper.mak文件中加入vs2012参数（你是其他版本就找到其他版本对应的地方，看看有没有你这个版本号，有的话就不用改了，么有就加上），如下图，在VL_MSVC
= 11.0的那里面已经有“11.00.50727.1”了，所以博主不用再加。如果你是vs2013，就找VL_MSVC = 12.0的，添上你的版本号就好啦。或者再没有就直接在圈红的那个位置自己写上~
3. &打开VS2012
x64 Native Tools Command Prompt（一般在开始菜单 vs对应文件夹下面就有），定位到/vlfeat-0.9.20目录下，为了防止有小盆友不知道怎么定位到，先贴图说明哈，宝宝们要改的就是cd后面改成自己放vlfeat的位置~
4. &定位到之后输入如下命令：
然后宝宝们就静静的等着它编译完成吧~完成之后并不会有说successful。。。命令提示还是静静的回到了初始状态就说明没问题啦：
4步完成后，将会在/vlfeat-0.9.20/bin目录下，新增一个win64目录，里面会有生成的vl.dll、vl.lib和一些test执行文件，后面MATLAB就能用这些啦。
&在MATLAB中完成最终配置
<span style="color:#. &首先打开MATLAB，输入语句：run('D:/codingtool/library/vlfeat-0.9.20/toolbox/vl_setup');将vlfeat路径添加进来。注意D:/codingtool/library是需要宝宝们改成自己放vlfeat的路径哒~
&切换MATLAB路径到vlfeat文件夹里面，直接在下图的红色横线那里选到就行：
3. &找到toolbox下面的vl_compile.m并直接运行之，然后静候成功啦~
<span style="color:#. &等他运行完成后可以在MATLAB里输入vl_version
verbose。配置成功的话就是下面的效果啦~
终于成功了好嗨森是不是~~~~~~博主还要嘱咐一句，为了以后能一打开MATLAB就能麻溜儿的用起来vlfeat，宝宝们还要多做一步：把刚才的run('D:/codingtool/library/vlfeat-0.9.20/toolbox/vl_setup');语句保存成一个叫做startup.m的m文件，放在你的MATLAB打开时的那个路径下（好像叫做启动路径吧），博主一打开MATLAB是这样的路径，所以你看startup就被我放在这里了。
然后就万事大吉啦~感谢观看喵，如果有帮到宝宝我很开熏~如果米有，那就遗憾啦T T

OpenCV（11）
第一步：下载opencv-2.4.9
第二步：运行opencv-2.4.9，我的目录为：F:\Program Files\opencv
第三步：环境配置
控制面板---&系统----&高级系统设置---&环境变量
然后设置path路径
最后确认：
至此环境配置已经结束
打开VS2012
文件---&新建项目
然后一些设置：
Debug右键属性
运行可能会出错：
之前在vs2012下编译一个opencv程序时，一直出现msvcp120d.dll文件丢失的提示信息，最初会在网上找dll下载，将其拖入系统文件夹再进行regsvr32命令操作，结果都没有解决错误，甚至在添加完成后再编译还会出现应用程序无法正常启动0xc000007b的错误。问题产生的主要原因是vs2012编译了一个用vs2013生成的dll,是在选择第三方库时选择vc版本时出现的问题，一定要多加注意。
vc8 = Visual Studio 2005vc9 = Visual Studio 2008vc10 = Visual Studio 2010vc11 = Visual Studio 2012vc12 = Visual Studio 2013
