Wish: Cross kernel executable

Hi,

May this example:

https://github.com/openembedded/meta-openembedded/pull/601

help @brgl to validate LVGL for linux port:

https://gitlab.eclipse.org/eclipse/oniro-blueprints/context-aware-touch-screen/meta-oniro-blueprints-cats/-/tree/brgl/cats-linux

I tested dialog on vending machine blueprint this way:

sudo su
export WAYLAND_DISPLAY=wayland-1
export XDG_RUNTIME_DIR=/run/user/1000
weston-terminal &
dialog-lvgl

Note since @brgl is writing cats in c++, may you consider this problem:

make deps ; make CC=clang++  run
