-[MGLGeoJSONSource mbgl_source] mapbox::geojson symbol(s) not found

Platform: iOS
Mapbox SDK version: v3.4.0-alpha.2 (static)

Attempting to use the static framework with v3.4.0-alpha.2 results in several undefined symbols errors.

Both arm64 and x86_64 architectures are reported as missing.

Undefined symbols for architecture arm64:
  "mapbox::geojson::convert(rapidjson::GenericValue<rapidjson::UTF8<char>, rapidjson::CrtAllocator> const&)", referenced from:
      mbgl::style::conversion::Result<mapbox::util::variant<mapbox::geometry::geometry<double>, mapbox::geometry::feature<double>, mapbox::geometry::feature_collection<double, std::__1::vector> > > mbgl::style::conversion::convertGeoJSON<rapidjson::GenericValue<rapidjson::UTF8<char>, rapidjson::CrtAllocator> >(rapidjson::GenericValue<rapidjson::UTF8<char>, rapidjson::CrtAllocator> const&) in Mapbox(geojson_source_impl.o)

Perhaps something changed during the CMake migration that keeps us from linking the static library to geojson-vt-cpp.

This appears to no longer be a problem — the static framework for v3.4.0-alpha.5 works as expected, as does one freshly compiled from master/alpha.6. Weird.
