Bug#836153: mutter: FTBFS on non-Linux: No package 'wayland-server' found

[Aaron M. Ucko]

Source: mutter
Version: 3.21.91-1
Severity: important
Justification: fails to build from source (but built successfully in the past)

The kfreebsd-amd64 build of mutter failed:

  checking for WAYLAND_SERVER... no
  configure: error: Package requirements (wayland-server >= 1.1.90) were not met:
  
  No package 'wayland-server' found

Please either patch mutter to work without Wayland libraries (at least
on platforms on which they are unavailable) or make the build
dependency unconditional.

Thanks!
