[yocto] do_rootfs error when including qt5 examples "cinematicexperience" and "qt5-opengles2-test"

[Malte Thiel]

Good day,

I included the following examples from "meta-qt5":

IMAGE_INSTALL += "cinematicexperience qt5-opengles2-test"

Everything works until "do_rootfs". I get the following errors:

[log_check] Error opening package -
qtdeclarative-dev-5.7.0+git0+d48b397cc7-r0.cortexa9hf_neon.rpm
[log_check] Error opening package -
qtdeclarative-staticdev-5.7.0+git0+d48b397cc7-r0.cortexa9hf_neon.rpm
[log_check] Error opening package -
qtdeclarative-dbg-5.7.0+git0+d48b397cc7-r0.cortexa9hf_neon.rpm

These packages exist (see attachment or the following link:
https://ibb.co/caJJ0k ). However, they have a size of 0 Bytes.

The dbg and dev-packages of other qt modules can be opened with the archive
manager and have actual content.

How do I fix this problem?
