If you want to share some units across several projects, you can put
them into one directory and add a lpk file.
This will speed up the compilation and avoids accidental double
creation of ppu files.

For the Lazarus sources all packages already have a lpk file and
lazbuild knows where to find them.

Well, that is the easy part:
The order of units is already figured out by fpc, the order of packages
is automatically solved by lazbuild.
Normally it is enough to pass to fpc only the main source file, for
instance the lpr file, and some search paths. The compiler will then
automatically search and compile all needed units recursively.
