[Lazarus] How to save compiled units for other programs to use?

[Crone, Thomas J.]

I'm using Lazarus IDE v1.0.2 on Windows 7.

With my old Delphi (v4), I'd compile a unit and copy the .dcu file to
the Delphi lib folder so other programs with "USES unitname" would find it.
I guess with Lazarus, I need to put the .ppu file somewhere? where?

Thank you
