he seguido este tutorial aquí como se mencionó exactamenteOpenCV en Generar en Visual Studio error de enlace
Ahora trato de ejecutar código OpenCV simple en Visual Studio, pero yo seguir recibiendo errores de enlace. Estoy tratando este OpenCV tutorial in particular
Aquí está el error me siguen dando:

Para el siguiente código:
// OpenCV_Proj.cpp : Defines the entry point for the console application.
//
#include "stdafx.h"
#include <opencv2/core/core.hpp>
#include <opencv2/highgui/highgui.hpp>
#include <iostream>
using namespace cv;
using namespace std;
int main(int argc, char** argv)
{
if(argc != 2)
{
cout <<" Usage: display_image ImageToLoadAndDisplay" << endl;
return -1;
}
Mat image;
image = imread(argv[1], CV_LOAD_IMAGE_COLOR); // Read the file
if(! image.data) // Check for invalid input
{
cout << "Could not open or find the image" << std::endl ;
return -1;
}
namedWindow("Display window", CV_WINDOW_AUTOSIZE);// Create a window for display.
imshow("Display window", image); // Show our image inside it.
waitKey(0); // Wait for a keystroke in the window
return 0;
}
int _tmain(int argc, _TCHAR* argv[])

}
he sido tratando de hacer que OpenCV funcione para VS2008 por un tiempo y cualquier ayuda con respecto a este problema se aplicará.
NOTA: En el archivo Léame del tutorial lo siguiente es lo que he seguido:
1) Add build\bin and one of build\{x86|x64}\{vc9\vc10\mingw}\bin to your system path (to use DLLs)
Add build\{x86|x64}\{vc9\vc10\mingw}\lib or
build\{x86|x64}\{vc9\vc10\mingw}\staticlib as library directories to your linker settings,
Add build\include and build\include\opencv as include directories to your compiler settings.
Any help with getting this to work is really appreciated.
Gracias. Eso solucionó el problema de los problemas del enlazador –
Hola, tengo una pregunta ... Si construimos el proyecto VS2010 usando CMake, ¿no debería crear todas las dependencias ...? Todavía recibo el mismo error – user1036908
