How to use developer WPEwebkit version with yocto.

[HarmElz]

Because of a GPU glitch in the stable version, I would like to check the developer version of WPEwebkit to see if the problem is still present in there, or might be solved. I copied the recipe for the 2.48.3 to 2.49.3, but when I run bitbake I get some errors.

The (I think) relevant information from the compiler:
wpewebkit/2.49.3/build/WTF/Headers/wtf/Ref.h:49:18: error: invalid use of incomplete type 'class WebKit::WebsiteDataStore'
| 49 | ptr->ref();
Source/WebKit/UIProcess/ProvisionalPageProxy.h:76:7: note: forward declaration of 'class WebKit::WebsiteDataStore'
| 76 | class WebsiteDataStore;

Can it be I need to update some dependency packages to newer versions for example?
Anyone a clue what the cause might be?
