Why not ? you can use
  subtarget=gtk2-debug

fppkg will see what is installed locally, and will not download what is
already there (unless the versions don't match).

The point is that the LCL must be installed in the package system, so fppkg
knows about it. That means an additional copy operation.

If you don't want that, then we must see about 'registering' local
build trees in fppkg; By this I mean that fppkg assumes that all is
installed under

~user/.fppkg/build/

(or something like it)

if you don't want this, you should be able to tell it that it should also look in 
e.g.

/path/to/lazarusdir/components/

To find additional packages there.
