Hmm this seems odd. At least wayland-scanner has a pkgconf variable:

  🕙14:51:21 alex@draig:buildroot.git/builds/x86_64  on  add-virtio-vulkan-vkmark:master [$!?⇡] 
  ➜  pkg-config --variable=wayland_scanner  wayland-scanner
  /usr/bin/wayland-scanner
  🕙14:52:16 alex@draig:buildroot.git/builds/x86_64  on  add-virtio-vulkan-vkmark:master [$!?⇡] 
  ➜  ./host/bin/pkgconf --variable=wayland_scanner  wayland-scanner
  /home/alex/lsrc/tests/buildroot.git/builds/x86_64/host/bin/wayland-scanner
  🕙14:52:29 alex@draig:buildroot.git/builds/x86_64  on  add-virtio-vulkan-vkmark:master [$!?⇡] 
  ➜

And the meson should find it with the normal dependency logic:

    wayland_scanner = find_program(wayland_scanner_dep.get_variable('wayland_scanner'))
