Qt6.8 + CMake: QML components cannot find qrc resources built by qt_add_resources

[Lopher]

I used the recommended modern method to construct qrc，But the path in the QML file cannot find qrc.

I have referred to:https://doc.qt.io/qt-6/qt-add-resources.html

CMake:

#imclient_resources.cmake
function(imclient_setup_resources)
    add_library(IMClientResources STATIC)

    qt_add_resources(IMClientResources "IMClientSvg"
        PREFIX "/icons"
        FILES
            resources/images/close.svg
            resources/images/maximize.svg
            resources/images/minimize.svg
            resources/images/restore.svg
    )

    target_link_libraries(IMClientResources PRIVATE Qt6::Core)
endfunction()

#imclient_app.cmake
function(imclient_setup_application)
    qt_add_executable(IMClientSrc
        src/main.cpp
    )

    target_link_libraries(IMClientSrc PRIVATE
        Qt6::Core
        Qt6::Quick
        Qt6::Qml
        Qt6::Gui
        IMClientQml
        IMClientResources
    )

    qt_import_qml_plugins(IMClientSrc)

    install(TARGETS IMClientSrc
        RUNTIME DESTINATION ${CMAKE_INSTALL_BINDIR}
        BUNDLE DESTINATION ${CMAKE_INSTALL_BINDIR}
    )
endfunction()

#Global CMake
qt_standard_project_setup()

TitleBar.qml

        // Minimize button
        TitleBarButton {
            width: buttonWidth
            height: buttonHeight
            visible: showMinimize
            iconSource: "qrc:/icons/minimize.svg"
            iconSize: titleBar.iconSize
            onClicked: if (targetWindow) targetWindow.showMinimized()
        }

        // Maximize/Restore button
        TitleBarButton {
            id: maximizeButton
            width: buttonWidth
            height: buttonHeight
            visible: showMaximize
            iconSource: targetWindow && targetWindow.visibility === Window.Maximized ?
                "qrc:/icons/restore.svg" : "qrc:/icons/maximize.svg"
            iconSize: titleBar.iconSize
            onClicked: toggleMaximize()
        }

        // Close button
        TitleBarButton {
            width: buttonWidth
            height: buttonHeight
            visible: showClose
            iconSource: "qrc:/icons/close.svg"
            iconSize: titleBar.iconSize
            hoverColor: closeButtonHoverColor
            onClicked: if (targetWindow) targetWindow.close()
        }

Application output:

qrc:/qt/qml/IMClient/qml/components/TitleBarButton.qml:21:5: QML Image: Cannot open: qrc:/icons/close.svg
qrc:/qt/qml/IMClient/qml/components/TitleBarButton.qml:21:5: QML Image: Cannot open: qrc:/icons/maximize.svg

@Lopher said in Qt6.8 + CMake: QML components cannot find qrc resources built by qt_add_resources:

Cannot open: qrc:/icons/close.svg

Because they are not there as you can see here:

    qt_add_resources(IMClientResources "IMClientSvg"
        PREFIX "/icons"
        FILES
            resources/images/close.svg

They are in :/icons/resources/images/close.svg
