Project folders

[Quasimojo]

I have project files in the following directory structure:

project
    ---- headers
    ---- source
    ---- build
    -------- debug
    -------- release
    ---- assets
    -------- graphics
    -------- audio

project
    ---- headers
    ---- source
    ---- build
    -------- debug
    -------- release
    ---- assets
    -------- graphics
    -------- audio

To copy to clipboard, switch view to plain text mode 

When I add, for example, one of the header files to my project in Qt Creator, I get an additional sub-folder (project -> headers -> headers -> file.h).

Is there a way to make the IDE observe my directory structure rather than stuffing it inside the default project folders?
