How can you measure the speed of light, when it is not possible to define an absolute point in space?

Since placement in space has to be relative to other objects, how does one measure the speed of light? If one photon is used as the base of the measurement, another photon going in the opposite direction would travel at twice the speed of light, which is of course impossible. What am I missing here?
