Quick question on optional builds with automake

[Kent Mein]

Hi I'm working on converting blender (www.blender.org)
To automake/autoconf etc...

I have the first part mostly working (producing 1 binary)
The next stage I'd like to do is get it to
build a second binary only when I type make blenderplayer

I'd also like to do a make webplugin (which will create
a shared library)

Any pointers on how to do this?
>From reading the docs I was guessing 
bin_PROGRAMS = blender
extra_PROGRAMS = blenderplayer
extra_LTLIBRARIES = blenderplugin.la

Thanks,

Kent Mein
