[Buildroot] [PATCH v3] gst1-plugins-good: add option for qmlgl plugin (qt5 plugin)

[Iñigo Huguet]

Hi Thomas.

I've tried to build gst1-plugins-good after applying your patch and 
removing the file 0001-configure-fix-qt-qpa-detection.patch. It builds 
with QT plugin enabled, so your solution works.

I'm going to prepare a new iteration of my patch, remember to commit 
yours one first or it won't work.

Thanks

Iñigo
