Compiling with "$staticprop!" or whatever

So it's like this:

Making a Spytech area, and I found the old TFC flag models in Hammer's model browser. So I go and stuff those in my map as Prop Statics, and in my compile log, it tells me I have to compile with $staticprop! or somehting. What's that, and how is it done?

Yup, that's it.



ITS LIKE IM REALLY SERVING AN EVIL OVERLORD!!
