If you put the headers within your project. As @CalaveraLoco's answer. Could using the relative path to access the header.

But it's better to include the project folder path into your project settings.

<ol>

blocks|key|2756339|text|在我的例子中，问题与导出类有关。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2756340|我有两个VS项目。让我们将它们命名为A和B。项目A使用项目B中的类；项目B使用OpenCV类。项目A没有使用(也没有链接)+OpenCV。(可以想象，项目A通过项目B使用openCV+)。|2756341|但是，如果B的任何导出类(由A使用)有一个OpenCV类型的私有成员(例如cv：：Mat)，那么在这种情况下，出现了错误C1083，尽管我在项目B中正确地链接了openCV。|2756342|我的解决方案是小心处理项目B的导出类的*.hpp文件中的包含。|2756343|希望它有用。|2756344|entityMap^0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|M|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|N|8|@]|9|@]|A|$]]|$1|F|3|G|5|6|7|O|8|@]|9|@]|A|$]]|$1|H|3|I|5|6|7|P|8|@]|9|@]|A|$]]|$1|J|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|K|$]]

In my case the problem had to do with exported classes.

I have 2 VS projects. Let's name them A and B.
Project A uses classes from project B; and project B uses classes of OpenCV.
Project A didn't use (neither link) OpenCV. (as you can imagine project A uses openCV throught project B).

But if any of the exported classes of B (used by A) had a private member of type OpenCV (cv::Mat, for example), in that case, the error C1083 appeared, although i had correctly linked openCV in project B.

My solution was to be carefull with the includes in the *.hpp files of the exported classes of project B.

Hope it's usefull.

that's funny but it seems that Visual Studio can't find the rigt headers files simply because there is not Opencv2 folder in the Opencv2 folder i mean that when reading the source code 

<blockquote>
 <code>#include &lt;opencv2/core/core.hpp&gt;</code>
</blockquote>

and following the include directories location,thus 

<blockquote>
 $(OPENCV_DIR)\build\include\opencv2
</blockquote>

he will try to find some 

<blockquote>
 $(OPENCV_DIR)\build\include\opencv2\opencv2\core\core.hpp
</blockquote>

which he will never find simply because the base directory is mismatch

to solve this problem just delete the base directory(opencv2) from the include 
directive :

<blockquote>
 <code>#include &lt;core.hpp&gt;</code>
</blockquote>

i hope this will help

You have to change Project > Properties -> change platform to x64 and the set the bin, lib and include folders again.

After this You have to also change "Solution platforms" tab from x86 to x64.

After this, you will be able to use OpenCV.

This question was asked several times, there are some answers, but this problem is more specific, the additional directories path is set correctly (files are found). 

Nevertheless building my project i get the following error:

<pre><code> fatal error C1083: Cannot open include file: 
 'opencv2/opencv.hpp': No such file or directory
</code></pre>

but i can right click on the file and open it in visual studio 2012?

<img src="https://i.stack.imgur.com/Ua10E.jpg" alt="File can be found without a problem">

I tried:

1) specifying the full path: WORKS!

<pre><code>#include &lt;D:\frameworks\opencv_2_4\build\include\opencv2\opencv.hpp&gt;
</code></pre>

2) Putting the file to C:\ Doesn't Work! (add. directories added)

3) Empty project with the same include syntax. (add. directories added). WORKS!

4) I've configured a VS2010 Version of the same project with CMake, and i have there the same problems.

Any hints what could be causing this error?

Visual Studio 2012: 'opencv2/opencv.hpp' : No such file or directory (C1083)
