sudo qemu=/path-to/qemu/build/qemu-system-x86_64 run_qemu.sh --git-qemu --cxl-debug

if [[ $_arg_cxl_legacy == "on" ]] || [[ $_arg_cxl == "on" ]]; then
		_arg_git_qemu="on"
	fi
	if [[ $_arg_git_qemu == "on" ]]; then
		qemu=~/git/qemu/x86_64-softmmu/qemu-system-x86_64
		qemu_img=~/git/qemu/qemu-img
		qmp=~/git/qemu/scripts/qmp/qmp-shell

@marcj303 Thanks for the report - yes this needs a clean up. There is some discussion about this in #17 - just need to go make it happen :)
