    i tried to reproduce a video but i got the error: undefined reference to `QSound::QSound(QString const&, QObject*)'
    i even do not understand why if libraries can be found by qt creator.

      @AliM93 Do you have

      QT += multimedia
      

      in your pro file?

        @AliM93

        multimedia module added? QSound included?

            @AliM93 So, do you have

            find_package(Qt5 COMPONENTS Multimedia REQUIRED)
            

            in your cmake file?

              i think the problem is still in the cmake, probably i have to add somenthing other?
              i post below parts of my cmake

              set(CMAKE_PREFIX_PATH "/opt/5.12.4/gcc_64/lib/cmake/")
              
              find_package(Qt5 COMPONENTS Multimedia REQUIRED)
              
              include_directories(
                  ${Qt5Core_INCLUDE_DIRS}
                  ${Qt5Gui_INCLUDE_DIRS}
                  ${Qt5Widgets_INCLUDE_DIRS}
                  ${Qt5PrintSupport_INCLUDE_DIRS}
                  ${Qt5Sql_INCLUDE_DIRS}
                  ${Qt5Multimedia_INCLUDE_DIRS}
                  ${Qt5MultimediaWidgets_INCLUDE_DIRS}
              
              
              
              
              
                  )
              
              
              

              and it's fine until i didn't code something requiring those libraries. this is way i do not have idea of what i am missing
              maybe something in

              target_link_libraries(agree_gui
              Qt5::Multimedia
              )

              ?

                @AliM93 said in Qmultimedia cmake trouble:

                include_directories

                This shouldn't be needed as you're using find_package.

                target_link_libraries(agree_gui
                    Qt5::Multimedia
                )
                

                is needed.
