Could NOT find Wayland (missing: WAYLAND_INCLUDE_DIRS)

The contenent of these varaibles is empty:
WAYLAND_INCLUDE_DIRS, WAYLAND_CFLAGS, WAYLAND_CFLAGS_OTHER, WAYLAND_LDFLAGS_OTHER

In other hand, the cotenent 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

Hi

You can try to add below packages into your local.conf

libwayland-egl libwayland-egl-dev

Problem is solved by adding these lines on the wpbackend-rdk recipe:

EXTRA_OECMAKE += " \

-DWAYLAND_INCLUDE_DIRS=${STAGING_INCDIR}/wayland \

-DWAYLAND_EGL_INCLUDE_DIRS=${STAGING_INCDIR} \

"
