I don't know your use case so I can not comment on what you have to do 
or should do.

Disregarding your use case ... to make it "work" (to stop cmake from 
complaining) all you have to do is move creation of the custom commands 
into the directory where the target is defined. The information required 
to create these commands may come from different scopes (e.g. you could 
maintain variables or global properties with the information required to 
construct the appropriate commands).
