Depends on the situation.
I sometimes staple a zip tie to wood and use that. Or use the zip ties with the screw hole on them.
Or in some other cases I use some plastic cable clamps as seen in this picture:

From Datacomm Electronics, except I cannot find a picture of them on their website. Don't use them in the extreme cold.. they snap
Or you can even just staple velcro to the wall and make it nice and easy to do/undo when you add/remove cabling.
