Yes, that is one way.

The IDE knows itself, so the lazarus.lpi is not really needed. I added  
the 'converter' path.

The IDE knows its search paths.
You can compile it via Tools / Build Lazarus. For myself I set a  
shortcut for that.
You can debug it via lazarus.lpi + F9 or via starting the IDE in gdb.

The IDE warns if a project file is missing. But I had not yet the time  
to show all missing files in one dialog - project inspector.

;)
