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

[DelazJ]

Hi all,
Thanks Peter. I got some time to give it another try. So I trashed my build
dir and restarted.
Now I'm stuck at

*In file included from ../src/3d/qgsskyboxsettings.h:*
*23,                 from ../src/3d/qgs3dmapsettings.h:*
*33,                 from src/3d/qgis_3d_autogen/**EWIEGA46WW/moc_*
*qgs3dmapsettings.cpp:9,                 from src/3d/qgis_3d_autogen/mocs_*
*compilation.cpp:9:../src/3d/qgsskyboxentity.h:*



*22:10: fatal error: Qt3DExtras/QCuboidMesh: Aucun fichier ou dossier de ce
type   22 | #include <Qt3DExtras/QCuboidMesh>        |
^~~~~~~~~~~~~~~~~~~~~~~~compilation terminated.[52/2925] Building CXX
object src/3d/CMakeFiles/qgis_3d.dir/**qgsabstractvectorlayer3drender*
*er.cpp.oninja: build stopped: subcommand failed.*

I don't know if it has anything to do but I had to fight against the "
Qt53DExtras" error to enable 3D













* CMake Error at /usr/lib/x86_64-linux-gnu/cmake/Qt5/Qt5Config.cmake:28
(find_package):   Could not find a package configuration file provided by
"Qt53DExtras" with   any of the following names:
 Qt53DExtrasConfig.cmake     qt53dextras-config.cmake   Add the
installation prefix of "Qt53DExtras" to CMAKE_PREFIX_PATH or set
 "Qt53DExtras_DIR" to a directory containing one of the above files.  If
 "Qt53DExtras" provides a separate development package or SDK, be sure it
 has been installed. Call Stack (most recent call first):
 CMakeLists.txt:404 (FIND_PACKAGE)*

Recipes I found in the list and the install file didn't seem to fix the
cmake so I set  set the QT53DExtras_DIR to
/pathtoQGISrepo/external/qt3dextra-headers/cmake*/Qt53DExtras* (in which I
found the missing file)

Thanks for any suggestion.
