Fix link library

- Address review comment https://github.com/opentrack/opentrack/pull/1306#discussion_r680484878
- Update ONNXRuntime module to use a specific `onnxruntime` target.
- Use OpenCV components instead.

NOTE:

ONNXRuntinme may provide their own ONNXRuntimeConfig.cmake and
ONNXRuntimeVersion.cmake in the future.
See https://github.com/microsoft/onnxruntime/issues/3124 for reference
