Consider the following code

import QtQuick
import Qt.labs.lottieqt

Item {
    LottieAnimation {
        quality: LottieAnimation.MediumQuality
    }
} 

When trying to build it with qmlsc the geneated code fails to build with

fatal error: lottieanimation.h: No such file or directory

   17 | #include <lottieanimation.h>

      |          ^~~~~~~~~~~~~~~~~~~

The Qt installation from the online installer doesn't seem to include a lottieanimation.h file at all, and manually building qtlottie doesn't install one either
