    I download files with msys :

    pacman -S mingw-w64-x86_64-gstreamer mingw-w64-x86_64-gst-plugins-base \
          mingw-w64-x86_64-gst-plugins-good mingw-w64-x86_64-gst-plugins-bad \
          mingw-w64-x86_64-gst-plugins-ugly mingw-w64-x86_64-gst-libav \
          mingw-w64-x86_64-gst-rtsp-server
    

    and I copy the pkgconfig to lib like that

    image.png

    and gsreamer-1.0.pc and gsteamer-video-1.0.pc exist

    image.png

    cmake like that :

    PKG_CONFIG_PATH=C:/gstreamer/1.0/msvc_x86_64/lib/pkgconfig:$PKG_CONFIG_PATH
    find_package( PkgConfig REQUIRED )
    pkg_search_module( GSTREAMER REQUIRED IMPORTED_TARGET gstreamer-1.0)
    pkg_search_module( GSTREAMER-VIDEO REQUIRED IMPORTED_TARGET gstreamer-video-1.0)
    

    but its not work

      I forgot about it and added it. the code shows it as added. but nothing happened. i keep getting the error. i'm sure the solution is very simple in linux. i wish it could be the same in windows.

        hey, the problem is that you need to write it like this:
        set(PKG_CONFIG_PATH=C:/gstreamer/1.0/msvc_x86_64/lib/pkgconfig:$PKG_CONFIG_PATH)
        this way it should work, I had the same problem last week

          Could not work on me :/

          Where do you install gstreamer and where do you install pkgconfig folder in lib ?

            https://stackoverflow.com/questions/10810279/finding-libraries-using-pkg-config-in-windows

            open one of the pc files and check if the prefix is correct.

            The installed pkg config path is basically fixed under lib. Do not try to change it.

                            I'm giving up...
                            Run the pkg-config command on the command line and you will see I would guess.
