The way I approach reusing common code is to have my common units in
local directories:

   ~/units           -- for code that is not yet considered stable
   /usr/local/units  -- for code that is considered stable

The first of these is added with a -Fu option in my ~/.fpc.cfg file, and
the second is added with a -Fu option in my /etc/fpc.cfg file. These
directories can also be added to your Lazarus compilation options.

Whenever I need to incorporate a unit I simply add its name to the
"uses" clause of the unit that needs to invoke code from the shared
unit. Lazarus seems to find the code when tracing, so it all just seems
to work.
