Hello,

after including the meta-qt5 and meta-boot2qt layer from https://code.qt.io/cgit/yocto, and adding them to my bblayers.conf, bitbake breaks directly while parsing the recipes:
---------------------------------------------
ERROR: ParseError at /home/yocto/projects/faseroptik-dunfell/build/../layers/meta-qt5/classes/cmake_qt5.bbclass:4: unparsed line: 'DEPENDS:prepend = "${QTBASEDEPENDS} "'                                                                                                                                    | ETA:  --:--:--

Summary: There was 1 ERROR message shown, returning a non-zero exit code.
---------------------------------------------

If i restart bitbake, the offending file changes now and then, but just for completion, here is the file:
---------------------------------------------
inherit cmake
inherit qmake5_paths

DEPENDS:prepend = "${QTBASEDEPENDS} "
QTBASEDEPENDS = "qtbase qtbase-native"
QTBASEDEPENDS:class-native = "qtbase-native"

The exact same layer with the exact same commit & files is working fine on the original boot2qt environment, but not on my environment.

My bblayers.conf looks like this:

LCONF_VERSION = "7"

BBPATH = "${TOPDIR}"
BBFILES ?= ""

On the working boot2qt environment poky 3.1.11 is used, i'm using poky 3.1.8.

Is there anything i can do to track this issue down? bitbake -v doesn't report more infos.

I appreciate any help here, thank you.

Best regards,
Kevin
