this is a problem of the path to include directory.
You can set directly the path in Project setting- C/C++ - General - Additional Include Directory: (c:/opencv/install/include) "Just example". Follow the picture. This will correct the problem with includes. 

<a href="https://i.stack.imgur.com/Tbvn1.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Tbvn1.png" alt="Additional include directory"></a>
You have to include additional library Directories as: c:\xxx\xxx\install\x64\vc16\lib 
x64 depends if you compiled opencv for 64 or 32 bits, vc16 is Visual Studio 2019. 

<a href="https://i.stack.imgur.com/aUNoU.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/aUNoU.png" alt="Additional library directories"></a>

The Additional dependencies on the following picture provide opencv_MODULE420.lib, where module is core, video, videoio, etc. If you have a problem here, The message symbol is not resolved will occur.

I recently did a tutorial for this here <a href="https://funvision.blogspot.com/2020/03/compile-opencv-4-for-visual-studio-2019.html" rel="nofollow noreferrer">funvision blog HERE</a>
in case you have a problem with installation by CMAKE. The tutorial includes the installation of GSTREAMER as well.

I am trying to install OpenCV with contrib modules for Visual Studio 2019 on a Windows 10 machine.

I previously had a working version in Visual Studio 2017, but have been unable to get either 2019 or 2017 working recently.

I have been using CMake to install this, adding the extra modules path before generating. Once I have built the ALL_BUILD and INSTALL files I am not sure of where I am meant to add the libraries and include paths and I have found conflicting results between tutorials and neither seem to work.

My code won't include the libraries and says that it can't open the source file.

Here is my code:

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

The error is:

Cannot open source file "opencv2/core/core.hpp"

I have reviewed the following materials to attempt to solve this but there are no up to date guides to include contrib modules nor any that work

我正试图在Windows 10计算机上安装带有VisualStudio2019控制模块的OpenCV。我以前在VisualStudio2017中有一个工作版本，但最近一直无法在2019年或2017年工作。我一直使用CMake来安装它，在生成之前添加额外的模块路径。一旦我构建了ALL_BUILD和安装文件，我就不知道我应该在哪里添加库和包含路径，并且我在教程之间发现了相互冲突的结果，两者似乎都不起作
