I didn't realize it was used by so many plugins. I noticed only the single
use of it in the source code and wondered why that warranted it's inclusion,
but the plugin thing makes sense.

I am just using QGIS core, but is there a way to build just the libraries
and not the app itself?

One potential issue with this is that I know that with QGIS 1.0 the
measuring tool didn't work properly in my embedded app unless the QGIS app
had been run on the machine. I'm not sure what caused this or if it has been
resolved, but that could be one reason I would need the app as well.

Thanks,
Dave
