Issues when linking Rust bindings to C++ code.

[scott-wilson]

I have the following PR here: https://github.com/AcademySoftwareFoundation/OpenImageIO/pull/4643/files

The test https://github.com/AcademySoftwareFoundation/OpenImageIO/pull/4643/files#diff-69049d4580f06ecbf7e0576174f3b9770f08ab0b1c284de13052fe3505253424R248 is throwing a link error due to the error undefined reference to OpenImageIO::v3_1_0::TypeDesc::TypeDesc(OpenImageIO::v3_1_0::basic_string_view<char, std::char_traits<char> >)'.

The cc command looks like this (OpenImageIO and OpenImageIO_Util is linked, and the search path points to the binary):

LC_ALL="C" VSLANG="1033" cc \
  -m64 \
  -Wl,--as-needed \
  -Wl,-Bdynamic \
  -lOpenImageIO \
  -lOpenImageIO_Util \
  -Wl,-Bstatic \
  -loiio-sys \
  -Wl,-Bdynamic \
  -lstdc++ \
  -lgcc_s \
  -lutil \
  -lrt \
  -lpthread \
  -lm \
  -ldl \
  -lc \
  -Wl,--eh-frame-hdr \
  -Wl,-z,noexecstack \
  -L /path/to/compiled/OpenImageIO/dist/lib \
  -Wl,--gc-sections \
  -pie \
  -Wl,-z,relro,-z,now \
  -nodefaultlibs

The OIIO team and I are scratching our heads, since it looks like the C++ side should all be happy, but I feel like I'm probably doing something very obviously wrong.
