I was trying to create sdk for Weston wayland image but iam facing these errors as shown below:

I am guessing my layer has qtbase_git.bb append file which includes :

PACKAGECONFIG_remove = " gl"
PACKAGECONFIG_append_pn-qtbase = " accessibility"
PACKAGECONFIG_append = " fontconfig freetype linuxfb"
PACKAGECONFIG_append = " ${@bb.utils.contains('DISTRO_FEATURES', 'opengl', 'gles2', '', d)} "

Now I found in some other yocto mailing list that if qtbase_git .bbappend has DISTRO_FEATURES  ''gles2" both xcomposite-glx and xcomposite-egl  cannot be enabled in qtwayland.bb file
 So which xcomposite should be removed.
I tried removing xcomposite-glx  and was able to create sdk but while testing my qt application after compiling that sdk it gave some errors as follows:

This application failed to start because it could not find or load the Qt platform plugin "wayland" in ".
available platform plugins are: linuxfd, minimal, offscreen, vnc, scb.
Reinstalling the application may fix this problem.


So what configuration should I use to build a successful Weston wayland image for QT.
Or what changes do I need to do in sdk to successfully launch wayland
