As you tell in your ppt:

The Mesa 3D project makes OpenGL and OpenGL ES rendering possible using CPU operations only and the Linux Framebuffer (without requiring a GPU)

my device has arm a53 without gpu. I build mesa-7.11.2 and yagear

	Usage: ./test/yagears2 -b Backend -e Engine

		Backends: egl-fbdev

		Engines:  glesv1_cm

when i run ./test/yagears2 -b egl-fbdev -e glesv1_cm, it gives me:

libEGL warning: failed to find any driver
libEGL warning: failed to find any driver
eglInitialize failed: 0x3001

building on Ubuntu 20.10, CMakeLists.txt should handle this case
