Check video/out folder and compare to newest version, no vo_wayland.* in the wayland 1.1 (0.1.7) version you're trying to make, only gl_wayland (the latest version has wayland listed in output if you modify configure to look for 1.1, but of course won't build, this is scary, our bleeding edge is already 6 months old for this project, hopefully jolla plan to move to wayland 1.2 soon)
