Virtual folders on build

[kleshas]

At the moment when i build a class named "glru" which is in folder "glu" i get "glu_glru.o". I really don't like that. I wan't it to be "glru.o" in a "glu" subdirectory. How can i make codelite build in my way? Also can i somehow use "real" folders instead of virtual in projects? Because i don't actualy understand why are the virtual folders needed. Are they making it easyer to compile or something?
