Nothing or at least not much really.
Dudes are just assuming and using what knowledge they have. Cap's shield is made of vibranium, it breaks, apparently no other place in the world has vibranium or at least that's what ppl are assuming, Wakanda is one of the biggest sources of vibranium, so Cap goes there to get his shield repaired or a new one.
Quite frankly, I hope his vibranium shield being broke is an after thought when it comes to the introduction of the Black Panther. I'd think he'd have a much more important reason for any after credit scene or cameo.
