ENH: Add if(TARGET) command
It is useful to be able to test if a target has been created. Often targets are created only inside conditions. Rather than storing the result of the condition manually for testing by other parts of the project, it is much easier for the other parts to just test for the target's existence. This will also be useful when find-modules start reporting results with IMPORTED targets and projects want to test if a certain target is available.
