        Hi @Jhankar-patel, and welcome to the forum.

        Can you show as your *.pro file please? Thanks.

        Qt has to stay free or it will die.

          Hi and welcome to devnet,

          You seem to be mixing your local system Qt and the conda installed version.

          How did you install OpenCV ?
          What about using the version provided by conda ?
