compile c++ code that uses openCV on Windows

I am trying to run fileName.cpp code that includes opencv2 library

I have opencv installed on my system but I didn't know why when I use:

Mex fileName.cpp

I got this error:

Cannot open include file: 'opencv2/opencv.hpp': No such file or directory

it seems there is a problem in linking opencv library to Matlab so the mex file can find it? how can I do that for windows OS.

thank in advance ...

mex does not know that it should link opencv2 if installed, and a lot of the time it would be a mistake to link it just because it is installed.

You should use the mex -I option to indicate the dictionary that contains opencv2, and the mex -L option to indicate the directory that contains the opencv2 DLLs

Thank you,

this is actually worked

from openCV folder: I used

>> mex -I'C:/Users/name/Downloads/opencv/build/include' -L'C:/Users/name/Downloads/opencv/build/x64/vc14/bin' fileName.cpp

and it worked

I also noticed that using

>>mexOpencv fileName.cpp

also worked...
