Detailed description
I wrote my code based on the example given on opencv github page for SURF matcher using CUDA.
When I try to build, i get the following errors:

All libraries seem to be linked properly and I am not getting any error while writing the code.
It would be great if anyone could say what the error is. Thanks!

I downloaded OpenCV from NuGet on MSVS 2017, and ran a code I had found on this very site:
#include "stdafx.h"
#include <opencv2/highgui/highgui.hpp>
#include <opencv2/core/core.hpp>
#include <opencv2/imgproc/imgproc.hpp>
using namespace std;
using namespace cv;
int main()
{
Mat image = imread("C:\\Users\\Chubak\\Pictures\\index.jpg");
if (image.empty())
return -1;
imshow("TEST", image);
waitKey();
return 0;
}
But when I run the code I get this extremely unintelligible errors that I don't understand:

I understand that unresolved externals error is related to missing obj files but don't they come with the NuGet Package?
I also found this question but all the links given in the answers are no longer working, so this may or may not be a duplicate.
I'm trying to compile the zeromq sources and I have the following error:
I'm using Visual studio 2013 update 4 / windows 7 x64
First of all I compile the libsodium library satisfactorily.
Then I link the libsodium header files directory path to additional dependencies and libsodium.lib to additional library directories. I also specify the name of library in additional dependencies.
I try to compile it under win32 architecture and x64 architecture but I get the same errors.
I know that a __imp prefix is used as a bridge to the function that I want to use so if I linked the libraries appropiately why do I get this error?

Thanks in advance.
You're probably compiling libsodium in a static way.
Try to compile it dinamically and link it again.
Such errors are also able to occur when you have a wrong set calling convention at your project.
First, let me start by saying I've read EVERY post, link, answer, etc I can find that points to Linking/External Symbol errors in Visual Studio/C++. With that said, here are the 27 errors I'm getting:

1>C:\Users\ME\Downloads\synergy-master\synergy-master\lib\MinSizeRel\ns.dll : fatal error LNK1120: 26 unresolved externals
Some background: I've downloaded Synergy from their GitHub and built it without error. Getting it to build took a small amount of hacking because they don't officially support Visual Studio 2013, but not overly difficult. I also built is using the latest Qt instead of the one they provide on their site (2010) I'm also using OpenSSL from SLProWeb, 32-bit full version.
Anyway, I cleared up a minor error or two in their code and tried to compile it first from command line, and second with VS GUI. Both spit out the 27 errors shown above. As I said, I've searched high and low trying to figure out what I've done wrong, but ultimately found nothing. I copied ssleay32.lib and libeay32.lib, with their .dlls, into the /ext/openssl/out32dll folder, where Synergy looks, which didn't work, so I pointed the linker additional libraries directory to it manually and also added it to the additional includes, and added the two .libs to Input>Additional Dependencies. Still no good.
In a last ditch effort, I added this to the top:
#pragma comment(lib, "libeay32.lib")
#pragma comment(lib, "ssleay32.lib")
#pragma comment(lib, "libeay32MD.lib")
#pragma comment(lib, "libeay32MDd.lib")
#pragma comment(lib, "libeay32MT.lib")
#pragma comment(lib, "libeay32MTd.lib")
#pragma comment(lib, "ssleay32MD.lib")
#pragma comment(lib, "ssleay32MDd.lib")
#pragma comment(lib, "ssleay32MT.lib")
#pragma comment(lib, "ssleay32MTd.lib")
while also copying the rest of the libs into the out32dll folder. This proved that it know the files existed, but still refused to resolve the External Symbol issue.
To me, it looks like it isn't properly loading libeay32.lib, which contains the crypto portion of OpenSSL that the compiler complains about....
I am trying to build OSGEarth using CMAKE and Visual studio 2013
I first downloaded Open Scene Graph 3.2 and the prebuild dependencies (small package) from this page. I generated the visual studio 2013 project and build/installed Open Scene Graph without much problem
After that, I downloaded the source of osgearth 2.5 and generated the Visual Studio 2013 project, using the same dependencies as for Open Scene Graph (I don't want to use the optional dependencies for the first build) and when I try to build the osgEarth project, I got the following error at the linking step :

The only think I was able to find is that all the missing method seems to be deprecated ODBC method, like this one
For additional information, the project got a reference to odbc32.lib in its inherited values.
Okay, stupid question... the odbc's dependencies were in the inherited values... but the checkbox indicated to the build process to use these dependencies was not checked. Once it was done, everything is good... I think I need either a coffee or a very big smack on the head...
I'm having some problems with using CEF in my application which uses the MD/MDd runtime library linking.
I have downloaded the latest build of CEF3 from cefbuilds.com and followed the instructions How to link CEF against a different run-time library.
I have built the "libcef_dll_wrapper" project after changing "Runtime Library" to "/MDd" and "Platform Toolset" to "v110" and then I've linked the resulting "libcef_dll_wrapper.lib" binary to my project.
However, when I try to build my project I get the following errors:
