[QGIS-Developer] Unable to build QGIS master due to multiple definitions of sipQgs3DAlgorithms

[Saber Razmjooei]

Hi Harrissou,

Here is my working one on Ubuntu 20.04:
-DCMAKE_PREFIX_PATH=~/src/QGIS_master/external/qt3dextra-headers/cmake/Qt53DExtras
-DQT5_3DEXTRA_INCLUDE_DIR=~/src/QGIS_master/external/qt3dextra-headers -D
QT5_3DEXTRA_LIBRARY=/usr/lib/x86_64-linux-gnu/libQt53DExtras.so
-DWITH_3D=True
-DQt53DExtras_DIR=~/src/QGIS_master/external/qt3dextra-headers/cmake/Qt53DExtras

I hope that works for you!

Kind regards
Saber
