Multiple application source directories


I am trying to compile an application with source files in multiple subdirectories. What is the best way to do this within the RIOT build system? I added "DIRS += ./<subdir>" to the application makefile, which results in compilation of subdirectory source files, but they are still not getting linked in.



Thanks for the suggestion, but adding to the SRC var in my application makefile doesn't appear to work (sources not getting compiled).
