How to compile with OpenCv 4.7.0

Hi,
I am trying to get the library built with OpenCv 4.7.0. Do you think this should be possible and what are the steps involved to accomplish that?
I downloaded the opencv and opencv_contrib source code and managed to compile it with visual studio 2022.
Also, I am not sure if VS2019 is a requirement.

I tried, and v 4.7.0 alllllllmost working. I did not get time to deeply check that.
Sebastian-Habiger commented
my progress on windows 11
- git could not checkout 4.7.0 due to the 260Chars limitation of older windows. To fix that long paths must be opt in.
Solution:git config --global core.longpaths true

I looks like 4.7.0 works at least on windows.
But there is something really strange. I've added bindings for the barcode Module from opencv_contrib package.
It does compile, but linking fails because it could not find the symbols of the barcode library.
I've checked if they are inside the Release path and they are.
So my question is: Do I need to opt in the barcode libraries somewhere in the node build package?
opencv_barcode470.exp
opencv_barcode470.lib
"checking for opencv libraries" does not list barcode

When set barcode to true inside misc.js of opencv-build it works just fine.
@UrielCh is there another option without messing with the code of opencv-build?
TripShade commented
This is how i do it for nestjs projects, should work for any version my example was 4.7.0-r3. The '# Fix code errors' part might not be needed. If it cries for node-gyp add it to the project or install it global.

hi, I'm currently working on a new opencv binding, so I'm less available for now.
