The targeting or spotlight usage altogether?
EDIT:
Targeted spotlight:
Consider the target and light position as 3d vectors.
The difference vector between these is defined as target-light.
Normalize this difference vector to get the direction from the light to the target. And you can use this direction vector in instructing OGL (GL_SPOT_DIRECTION).
