Detailed description

Building OpenCV with Gstreamer using CMake 3.22.1 succesfully generates the solution file after configuring all the paths. When compiling the solution in both Debug and Release mode, opencv_videoio fails due to an unresolved external link to _imp_gst_audio_info_from_caps.

Solution: Since I don't know how to edit the CMake files for this, I succeeded in getting it to work by adding the path to the gstaudio-1.0.lib to the opencv_videoio project in Visual Studio:
\gstreamer\1.0\msvc_x86_64\lib\gstaudio-1.0.lib
opencv_videoio -> properties -> linker -> additional dependencies

I suspect the real solution is to add that to the CMake configuration files for videoio
