Environment variables, their defaults and relative paths, where the defaults 
usually depend on paths specified at build time.

The main environment variable for this is KDEDIRS. Quite like PATH it is a 
list of (colon separated) directories, where the order indicates the 
respective priority.

Then, depending on the resource, there is an associated relative 
path/subdirectory, e.g.

share/apps/
KDE application data

config/
KDE configs

lib/kde3  (lib/kde4)
KDE plugins (as a resource called modules)

basically KDEHOME (default $HOME/.kde/) is also such a base directory, the one 
with highest priority.

kde-config (kde4-config) is a nice command line tool which one can use to 
determine such paths for example for using in scripts (the KDE start script 
startkde uses this as well, at least it does in KDE3)

Cheers,
Kevin
