for GBM: I've not been able to get it to work myself on my htpc yet. There is still a bug that seems to affect older intel cpus/gpus.
In theory you would just switch the Exec_start command of the systemd script to run /usr/bin/kodi --standalone directly instead of openbox

thanks @wsnipex 
I started to compiling out for the first time, can I ask if it's right?

git clone https://github.com/xbmc/xbmc kodi
cd $HOME/kodi
sudo make -C tools/depends/target/crossguid PREFIX=/usr/lib/x86_64-linux-gnu/
mkdir $HOME/kodi-build
cd $HOME/kodi-build
cmake ../kodi -DCMAKE_INSTALL_PREFIX=/usr/lib/x86_64-linux-gnu/ -DCORE_PLATFORM_NAME=gbm
cmake --build . -- VERBOSE=1 -j4
