You can add a layer which will set LAYERSERIES_COMPAT for another layer, but it needs to be parsed before the layer you want to change, e.g.:
https://github.com/webosose/meta-webosose/blob/thud/meta-qt5-compat/conf/layer.conf
it's useful to use this layer also to implement whatever modifications are needed to make the layer to be actually compatible with the release you're using, like:
https://github.com/webOS-ports/meta-webos-ports/tree/zeus/meta-qt5-compat

Hi,
have an issue with a layer which doesn't have the current dunfell release in it's LAYERSERIES_COMPAT_
-> can I overwrite it somehow in a different layer or local.conf?
-> can I configure the error "...is not compatible with the core layer..." to a warning?
cheers, Thomas
