What astronomers look for is a construct called a Dyson Swarm. It is basically a shitload of artificial objects such as rotating habitats which surround a star. There would be an unmistakable infrared signature from such an object. We should see them if they are there.
I've never been convinced by the argument that technological civilizations will inevitably build these and I'm definitely not convinced that a civilization would eventually do this with every system in the galaxy. It's based on the animal instinct to multiply, something I believe all life-forms would lose when they inevitably augment themselves with technology.

Only two things are infinite, the universe and human stupidity, and I'm not sure about the former.
