Hello Sujay S,
The netsurf recipe you pointed to seems not to be supported on the newer branches of the Open Embedded project. Looks like it’s no longer being worked on.
You could try adding this recipe to your BSP setup but you are most likely going to find compatibility problems unless you use one of the older BSPs or branches.
The official website for the NetSurf project is below, you could create your own recipe that fetches and compile the code for NetSurf, although it’s not a trivial task.

My apologies for the inconvenience.
Regards,
