[QGIS-Developer] Compiling QGIS with 3D failing

[matteo]

Hi all,

I got an error when compiling QGIS with 3D support on Debian SID:

......a bunch of similar lines......

/usr/bin/ld: CMakeFiles/python_module_qgis__3d.dir/3d/sip_3dpart5.cpp.o:
in function `sipQgs3DAlgorithms::sipProtectVirt_loadAlgorithms(bool)':

if the 3D support is deactivated then all is working fine.

not sure which commit introduced this problem.

Cheers and thanks
