[QGIS-Developer] Fail compiing WITH_3D on ubuntu 20.04 - Qt53DExtras config files missing

[Denis Rouzaud]

I believe you have to set this on 20.04

-DQT5_3DEXTRA_LIBRARY=/usr/lib/x86_64-linux-gnu/libQt53DExtras.so
-DQT5_3DEXTRA_INCLUDE_DIR=/root/QGIS/external/qt3dextra-headers
-DCMAKE_PREFIX_PATH=/root/QGIS/external/qt3dextra-headers/cmake
-DQt53DExtras_DIR=/root/QGIS/external/qt3dextra-headers/cmake/Qt53DExtras

Ciao,
