I also tried the prerelease v5.2.14-3-rc1, here the result looks like this.

The fail for the prerelease seems to be handled in #185

[elguero]

It would appear that you have created the issue to the wrong repo. The rpms you reference are not maintained by the evdi team.

This issue has been solved by the evdi team and current master of displaylink-rpm is able to build against the devel branch of evdi.

displaylink-rpm/displaylink-rpm#121

[msandres13]

Of course, you are correct.
I learned that investiating in the problem.
I will close the ticket.

Thanks for the reminder
