Hello Maxim,

I recommend you to read the tutorial at . It addresses all of your 
questions. See below:

You can refer to any subdirectory in the source with 
$(srcdir)/your_subdirectory. For including purposes you'd use -

You can put full paths to these files in your or create one for every subdirectory and refer each file by its name. See 
SUBDIRS in the tutorial.

This is covered on page 92 of the tutorial, "Conditinals: usage"

You can link with system libraries or with libraries created in your own
