meta-toolchain-qt6 build failed

Walter-X

I'm trying to build the toolchain sdk with Yocto (Kirkstone) on Ubuntu 22. The build fails with errors in bitbaking qtpdf:

I tried to remove qtpdf from packagegroup-qt6-addons.bb or adding EXTRA_OECMAKE with -DFEATURE_qtpdf_build=OFF. But nothing solves the problem.
Has anyone also this error an a solution for it?

I found the solution at https://professoreletrico.com/cursos/yocto/error-building-qt6-toolchain-in-with-yocto/ - many thanks to Djones Boni.

Add a file qtpdf_git.bbappend to your meta-layer and add this content:

DEPENDS += " cups"
