wpebackend-rdk Build Error on YOCTO Kirkstone with i.MX6

Question

I am trying to build WPEBackend-rdk on kirkstone for the i.MX6 but I found this error:

Could NOT find Wayland (missing: WAYLAND_INCLUDE_DIRS)

The content of these variables is empty:

• WAYLAND_INCLUDE_DIRS,
• WAYLAND_CFLAGS,
• WAYLAND_CFLAGS_OTHER,
• WAYLAND_LDFLAGS_OTHER

In other hand, the content of these variables is:

• WAYLAND_FOUND: 1
• WAYLAND_LIBRARIES: wayland-client;wayland-server
• WAYLAND_LINK_LIBRARIES: /[build_folders]//work/cortexa9t2hf-neon-oe-linux-gnueabi/wpebackend-rdk/1.20221201-r0/recipe-sysroot/usr/lib/libwayland-client.so;/[build_folders]//work/cortexa9t2hf-neon-oe-linux-gnueabi/wpebackend-rdk/1.20221201-r0/recipe-sysroot/usr/lib/libwayland-server.so
• WAYLAND_LIBRARY_DIRS: [build_folders]/work/cortexa9t2hf-neon-oe-linux-gnueabi/wpebackend-rdk/1.20221201-r0/recipe-sysroot/usr/lib
• WAYLAND_LDFLAGS: -L/[build_folders]//work/cortexa9t2hf-neon-oe-linux-gnueabi/wpebackend-rdk/1.20221201-r0/recipe-sysroot/usr/lib;-lwayland-client;-lwayland-server

Knowing that the Wayland dependency is set and the

• PREFERRED_PROVIDER_virtual/wpebackend = "wpebackend-rdk"
• The wpebackend-rdk recipe is: wpebackend-rdk_1.20221201.bb
• The wpebackend-rdk sources: master

Can you help me please?
