[CMake] Setting the directory associated with a target

[Mathias Gaunard]

Hi,

I've recently moved from using the simple Makefile generator to the 
Eclipse CDT one, and I have noticed that targets only appear in the 
directory in which they were created.

Is there a way to specify which directory a target should appear in?

I tend to define "parent" targets when the first "child" target is 
created, which means it doesn't appear in the right place.
