Qmultimedia cmake trouble

AliM93

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?

Pl45m4

@AliM93

multimedia module added? QSound included?

AliM93

i am using cmake file, and i added all the components.
and yes i include all the things
thanks

@AliM93 So, do you have

find_package(Qt5 COMPONENTS Multimedia REQUIRED)

in your cmake file?

AliM93

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.
