Hi all. I am trying to use mexOpenCv for a college course. It seems to require Microsoft Visual C++ 2015 which I cannot seem to find anywhere. I managed to get Microsoft Visual C++ 2019 installed and Matlab is currently using it. Below is the message I get when I try to use mexOpenCV:
Error using mexOpenCV (line 63)
The OpenCV libraries were built using 'Microsoft Visual C++ 2015'.
Your compiler is 'Microsoft Visual C++ 2019 (C)'.
These compilers may not be compatible.
Note that you can select a compiler using 'mex -setup' command.
Running mex -v -setup returns the following
>> mex -v -setup
Verbose mode is on.

Found installed compiler 'Microsoft Visual C++ 2019 (C)'.
MEX configured to use 'Microsoft Visual C++ 2019 (C)' for C language compilation.
The mexOpenCV specifically calls out the 2015 version and will error out without. I need some help finding a way to install the Microsoft Visual C++ 2015 compiler so that Matlab see it (I've tried this Announcing Visual C++ Build Tools 2015 – standalone C++ tools for build environments link but that didn't work) or something that allows me to access OpenCV from inside Matlab.

I had the same problem with mex setup. When I tried the below steps it worked for me. I hope this will help you.
Uninstall all the versions of Visual studio from your pc. Then download the visual studio 2017 from below link.
https://visualstudio.microsoft.com/vs/older-downloads/
Then please run the following command in MATLAB terminal.
>>mex -setup
It should automatically detect the Visual studio c++ compiler for you and it will also set it if one compiler is installed. You can also change the compiler which you want to use If you have a more than one compiler installed like MinGW compiler.
