OSG links to FontConfig
When the OFI builds OSG as a dependency, and FontConfig is available on the build system, then OSG will link to FontConfig. This causes the OFI to not load on end-users' machines if they do not also have FontConfig installed.
Fix this by telling OSG to not use FontConfig even if it is available. This is fine because FontConfig's features are not needed for the OFI.
