以前，windows下配置OpenCV一直不太方便：总是要手动添加lib，添加include，还要配置PATH使得程序运行时候能找到dll文件。
每次新建一个使用OpenCV的工程都要手动添加，很麻烦；而且，有时候需要不同版本的OpenCV测试。如果从32位模式切换到64位模式，又需要替换一次配置。。一旦有一个配错了，就总是徘徊在各种配置项的检查上。
后来，看到了freedomshe用属性表进行配置，其提供的属性表文件确实方便，但是还是需要手动配置OpenCV环境变量、追加OpenCV中的bin目录到PATH上（bin中有dll文件）。能不能不配置？（免得保不准自己又要重启机器...）
答案当然是可以！
配置OpenCV环境变量的目的在于，include路径、lib路径都使用这个前缀，能减少打字的次数；同时也是要把opencv的几个dll文件所在路径，追加到系统PATH上。
只要我们在属性表文件中自行定义OpenCV根目录，添加include路径、lib路径，添加dll目录，以后使用OpenCV的项目只需要导入这个属性表就OK了，太简单了！
当然，以前的老版本中的各种dll和lib分成好多个文件，现在的版本如果编译了opencv_contrib也会有额外的dll和lib，这些需要的时候再添加就好了。
废话不多说，这是OpenCV3.0.0的通用属性表文件opencv300.props
<?xml version="1.0" encoding="utf-8"?>

如果是opencv3.1那么lib只需要配置opencv_world310，对应的属性表文件为：
<?xml version="1.0" encoding="utf-8"?>
<!--

当然有时候需要使用OpenCV_contrib，那么编译好contrib后就增加了很多dll和lib，对应的属性表文件是这样的（opencv3.1版）：
<?xml version="1.0" encoding="utf-8"?>
<!--

===========
P.S. 有人可能会问，上面的属性表XML文件里面的各属性是如何确定的？属性值容易设定，属性名确实不是一眼看出来的。
可以通过新建一个工程，在工程的属性中手动设定VC++、C/C++、链接器等条目中的项，进行设定后vs2013会写入到<your_project_name>/<your_project_name>.vcxproj.user这个文件中。手动在GUI界面中设定了需要的属性后，查看.vcxproj.user文件，把需要的属性剪切到属性表文件中，以后同类型的工程就可以仅仅使用此属性表文件进行配置了。比如dll的路径，通过当前工程的属性->调试->工作目录进行设定：
