That's a mistake.

It's mostly for development, using rasqal with redland as it's backend
store.  This is not something anyone but me should really be using, as it
gives you a recursive dependency.  Remove it from the project.

The choice of which things to build are defined in win32_rdf_config.h
so you can disable either or both of those.  On POSIX systems,
rdf_config.h is generated by configure.  Since win32 doesn't
do that, it's a static file you'll have to edit if you change
the modular parts, such as stores.

It's all open source, you can edit the IDE's project files.  There
are plenty of ways to change them.
