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. ---

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!! ---
