opencv 3.0 visual studio community 2017 compilation LINK errors - c++

Question

I installed opencv 3.0 in my windows10 64 bit. I created a C++ project in visual studio community 2017 and did all these steps provided in opencv documentation (local method in this link which are:
1- creation of environment variable:
OPENCV_DIR C:\Program Files\opencv\build\x86\vc11
With I added in user and system Path as follow
%OPENCV_DIR%\bin
2- In my project I added in Properties -> C/C++ -> additional include repositories:
C:\Program Files\opencv\build\include
3- Properties -> Link -> General:
$(OPENCV_DIR)\lib
$(OPENCV_DIR)\staticlib
I included staticlib because at first the compiler didn't find opencv_core300d.lib while this one exists in staticlib, so I added it.
checked YES for use library dependency entries
4- Properties -> Link -> Entry:
opencv_core300d.lib
opencv_highgui300d.lib
opencv_imgproc300d.lib
opencv_ml300d.lib
opencv_ts300d.lib
with Herited values:
kernel32.lib
user32.lib
gdi32.lib
winspool.lib
comdlg32.lib
advapi32.lib
I got more 800 errors all related to mismatch between values in .obj files related to opencv_core300d.lib:
1>Source.cpp

I tried to resolve the issue by checking similar answers to similar errors and according to this answer it's due to different versions of the compiler. If so, how to correct it?
Sample code used to test that opencv works:
#include <opencv2/core.hpp>
#include <opencv2/imgcodecs.hpp>
#include <opencv2/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], IMREAD_COLOR); // Read the file
if (image.empty()) // Check for invalid input
{
cout << "Could not open or find the image" << std::endl;
return -1;
}
namedWindow("Display window", 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;
}
I need help!
Thank you.

These error is due to different build version of the opencv library. You can download the pre build binaries for your compiler version if available or else you need to build OpenCV from source using cmake. In your case you require binaries built for vs2017 i.e. _MSC_VER 1900.
