Cannot load qml from parent folders

[tham]

How could I load qml from parent folders?

Following are my qrc

<RCC>
    <qresource prefix="/">
        <file>../../qml/camera_settings/camera_select/CameraSelectMain.qml</file>
        <file>CameraSelectMain.qml</file>
    </qresource>
</RCC>

Both of the files with the same contents, but I cannot load the CameraSelectMain.qml with the first url

#include <QApplication>
#include <QQuickStyle>
#include <QQuickWidget>

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);

    QQuickStyle::setStyle("Material");

    QQuickWidget widget;
    //this url do not work
    widget.setSource(QUrl("qrc:/../../qml/camera_settings/camera_select/CameraSelectMain.qml"));
    //this url work
    //widget.setSource(QUrl("qrc:/CameraSelectMain.qml"));
    widget.show();

    return a.exec();
}

How could I let the QQuickWidget able to load the qml file from
"qrc:/../../qml/camera_settings/camera_select/CameraSelectMain.qml"?Thanks

@tham
you could do the following:

in your qrc:

<file alias="CameraSelectMain.qml">../../qml/camera_settings/camera_select/CameraSelectMain.qml</file>

in your main():

widget.setSource(QUrl("qrc:/CameraSelectMain.qml"));
