Building from source on Windows 10

C++

Hi,
I am attempting to build OpenCV from the sources using Windows 10 and Visual Studio 2022 c++ 17.
I have followed the instructions from the OpenCV website. I have installed python, cmake and no end of other stuff. When I click “configure” in cmake there is an error and the cmake output log says “The system is: Windows - 10.0.19044 - AMD64”

I have scoured the internet and I cannot find any guidance as to what the issue might be.

Is anyone able to shed any light.
Many Thanks.

Not sure there is anything more to add.
Would you like to be more specific.
Thanks.

“Error in configuration process, project files may be invalid”

I found additional text…

CMake Error at CMakeLists.txt:113 (enable_language):
Generator

Visual Studio 17 2022

could not find any instance of Visual Studio.

Configuring incomplete, errors occurred!
See also “X:/OpenCV/build/CMakeFiles/CMakeOutput.log”.

I have Visual Studio 2022 installed and it works fine.

I think the installer for Visual Studio 2022 is a bit funky.
I went into the Installer to ensure I had the right modules and it said I did not have a version of VS2022 installed which is really weird because I was using it just fine.
So I reinstalled VS2022 and then I could not compile a project because it could not find windows.h >mega funky.
So I reinstalled VS2022 a third time, I could compile my c++ projects and now cmake seemed to work fine.
I built OpenCV using cmake and I was able to open OpenCV as an sln and I am currently compiling it within VS2022.
Such my life!!
