Hey guys,

I’m just trying to include the latest OpenCV (4.10.0) into my build using Github Actions but after the successfull extraction I’m missing **opencv\_world4100.dll** and **opencv\_world4100d.dll** inside the **opencv/build/x64/vc16/bin** directory (there are only opencv\_world4100.pdb and opencv\_world4100d.pdb files).  
When I’m extracting the same package on my laptop using the same command (./opencv.exe -o"./" -y ) the \*.dll files are in a bin folder. Don’t know on which side the problem is, Github Actions’ or OpenCV’s.  
Anyway, there are commands that I’m using to download and extract OpenCV on the virtual machine (YML file):

```auto
      - name: Download and Extract OpenCV
        shell: pwsh
        run: |
          curl -L "https://github.com/opencv/opencv/releases/download/4.10.0/opencv-4.10.0-windows.exe" -o opencv.exe
          ./opencv.exe -o"./" -y 
          echo "OpenCV extraction complete."
          echo "OPENCV_LATEST=$(pwd)/opencv/build/x64/vc16" >> $env:GITHUB_ENV

```

Verification process:

```auto
      - name: Verify OpenCV Directory
        shell: pwsh
        run: |
          echo "OPENCV_LATEST is: ${{ env.OPENCV_LATEST }}"
          dir ${{ env.OPENCV_LATEST }}/..
          dir ${{ env.OPENCV_LATEST }}
          dir ${{ env.OPENCV_LATEST }}/bin
          dir ${{ env.OPENCV_LATEST }}/lib

```

The Github’s output:
