[oe] [meta-qt5] What is the proper way to enable OpenGL ES v2 without using .bbappend

[Petr Nechaev]

Hi All,

 what is the proper way to tell meta-qt5 to build with OpenGL ES v2 support
without using a .bbappend file like this:
----------------------
# switch to GLES 2 support
PACKAGECONFIG_GL = "${@base_contains('DISTRO_FEATURES', 'opengl', 'gles2',
'', d)}"
----------------------

I encountered several boards with have only GLES support, no desktop OpenGL.

AFAIK there is no "opengles" distro feature (in DISTRO_FEATURES)
standardized yet.
Googling resulted in

Should we define something opengles-2, opengles-3 etc for DISTRO_FEATURES?

Thanks,
