fatal error: LibWeb/CSS/Enums.h: No such file or directory

I checked out ladybird and followed the build steps and described in the BuildInstruction.md file and received the following error:

I retried and set the SERENITY_SOURCE_DIR option on cmake to point to a running build of sOS, but received the same error.

It looks like the Enums.h file is generated and is in the build output directory and I don't see a -I on the command line pointing to it. Am I missing a step during build?

Does this still reproduce on latest master? There have been updates to the build since this issue was created. But even two weeks ago I would expect the build not to be broken. It's often the case that a good old rm -rf Build will fix this kind of issue. For more build issues though, please ask in the SerenityOS discord in the #build-problems channel.
