Is it possible to cmake tensorflow-lite GPU with backend openGL?

I saw this part TFLite GPU backend uses OpenGL ES 3.1 compute shaders or OpenCL. in

But when I built it with -DTFLITE_ENABLE_GPU=ON, it seems it only builds the openCL codes.

Checked the CMakeLists.txt, couldn’t even find any openGL source included by the build target.

So I got a bit confused, is it possible to cmake tesorflow-lite with GPU backend openGL?
