CMake install target on Windows does not install libs into correct subdirs

[MrMoose]

System Information

OpenCV version: 4.9.0
Operating System / Platform: Windows (11)
Compiler & compiler version: MSVC17 (Visual Studio 2022)

Detailed description

I'm building a custom and quite minimal OpenCV from source using CMake. The build runs through but the resulting installed package could not be found by CMake find_package(). Debugging into it I noticed it is installed into the wrong folders.

The resulting installed dir contains:

etc
include
staticlib
LICENSE
OpenCVConfig-version.cmake
OpenCVConfig.cmake
setup_vars_opencv4.cmd

and in staticlib there is:

OpenCVConfig-version.cmake
OpenCVConfig.cmake
OpenCVModules-release.cmake
OpenCVModules.cmake
opencv_core490.lib
opencv_features2d490.lib
opencv_flann490.lib
opencv_highgui490.lib
opencv_imgproc490.lib
opencv_video490.lib

According to the CMake finders and examples in the web the directory is supposed to be x64\vc17\staticlib.
As a result, CMake finders cannot find the package, which I consider a serious issue.

Steps to reproduce

Build from source on Windows, observe subdir.

Issue submission checklist

• I report the issue, it's not a question
• I checked the problem with documentation, FAQ, open issues, forum.opencv.org, Stack Overflow, etc and have not found any solution
• I updated to the latest OpenCV version and the issue is still there
• There is reproducer code and related data files (videos, images, onnx, etc)

This might actually be a bug in MSVC 17.10. Others have this problem too. I reported it there with additional info. Not sure though

Try the latest OpenCV version or apply these patches: #25632 and #25638

[MrMoose]

Yes, it boiled down to the re-versioning of the toolchain from 14.3 to 14.4. Didn't know you already had this patched. I can confirm the fix. Closing this.
