The release tarball ships its CMake package files under lib/, but
onnxruntimeTargets.cmake resolves the library as <prefix>/lib64. Ubuntu
is multiarch, so CMake does not search lib64 for packages and ld.so does
not search /usr/local/lib64 at all, leaving find_package(onnxruntime)
failing on a stock install. Keep the libraries in lib64, move only the
package files to lib/cmake, and add lib64 to the linker path.
ONNX Runtime is a configure-time dependency for every build, not only
for the yolo_onnx engine. The event loop no longer inspects the input
id, so it grabs on any input rather than specifically on tick.
Deletes the yoloworld_onnx engine, the CLIP BPE tokenizer, the standalone
test binary and both export scripts. Drops the update_vocabulary input and
the yoloworld_onnx/open_vocab dispatch from main.cc, along with the now
unused Engine::set_labels. Documentation follows.
