I recently installed cURLpp from NUGET in visual studio. Everything installed correctly and when I try to use cURLpp I get the following error:
Severity Code Description Project File Line Suppression State Error LNK2019 unresolved external symbol __imp__curl_easy_setopt referenced in function "public: void __thiscall curlpp::internal::CurlHandle::option<void *>(enum CURLoption,void *)" (??$option#PAX#CurlHandle#internal#curlpp##QAEXW4CURLoption##PAX#Z) Project1 C:\Users\Joel\documents\visual studio 2015\Projects\Project1\Project1\main.obj 1
This error stops happening when I remove #include Options.hpp

I installed OpenCV-v2.4.11 from NuGet Package Manager in Microsoft Visual Studio 2019. However, I can't get working this code:
#include <opencv2/opencv.hpp>
int main()
{
cv::Mat A;
return 0;
}
I got these errors:

Answered in comments below the question.
The compiler toolkits in vs 2019 are not compatible with opencv in Nuget or else now,there are two way you can choose:
1.compile opencv by yourself,you need to rewrite makefile.
2.use it in vs2015.
I have linked libcurl for linker still getting below error:
Error LNK2019 unresolved external symbol curl_global_init referenced in function "void _cdecl getRequest(void)"
I'm attempting to upgrade a project written in C++ in VS 2005 to VS 2010. After I run the upgrade wizard, I try and build the project and I get a bunch of LNK2019 errors.
For further clarification, this projects builds a DLL which is used by our Product Lifecycle Management system named Teamcenter.
At this point, I'm kind of stumped. The project compiles in VS 2005 in Debug without any issues.
Any ideas?
Here is a snippet of the error:

I'm working with Cplex and visual studio 2010. I have added the include and linked the .lib. I have a lot of errors like the following:
Error 1
error LNK2019: unresolved external symbol "public: void __thiscall IloAlgorithm::extract(class IloModel)const "
(?extract#IloAlgorithm##QBEXVIloModel###Z) referenced in function

Error 2
error LNK2019: unresolved external symbol "public: __thiscall IloCplex::IloCplex(class IloEnv)"

Please, can you help me to solve this problem?
I had the same problem and I solved it including ilocplex.lib to the additional dependencies.
However, I have Cplex for Visual Studio 2008.
