/// Provide a convenient way to access ittapi functions that may have not been initialized. The
/// `ittnotify` library has a static part (e.g., `libittnotify.a`) and a dynamic part (e.g.,
/// `libittnotify_collector.so`, VTune Profiler). The static part provides the ITT symbols to the
/// application but these may not be resolved to actual implementations in the dynamic part--the
/// data collector.
