Hello,
I am currently running QGroundControl v5.0 (stable release) with Qt 6.8.3.
Previously, I followed the official Qt guide for Android to successfully build and install the stable QGC v4.4 version with Qt 5.15.2 for both Android and Windows desktop.
However, since that version does not include the 3D View, I am now testing the newer QGC v5.0 stable release with Qt 6.8.3 to check if 3D View is supported.

I initially encountered multiple undefined symbol linker errors related to graphene, jpeg, and libpng while building QGroundControl.
To address this, I downloaded the required graphene and libpng libraries as ZIP files, extracted them, and manually added their include and lib directories to the CMakeLists.txt file. I also linked the static libraries (graphene-1.0, jpeg, and libpng.a) using target_link_libraries().
Could you please confirm if these manual changes are the reason I’m now experiencing the current linker errors? I suspect the issue might be related to architecture or compatibility mismatches.
