 A utility for locating OpenVINO™ libraries on a host system. It will attempt to find the OpenVINO
 shared libraries in:
+- the `OPENVINO_BUILD_DIR` environment variable (pointed at a locally-built OpenVINO repository)
 - the `OPENVINO_INSTALL_DIR` environment variable (pointed at the top-level OpenVINO installation,

 - the `INTEL_OPENVINO_DIR` environment variable (same as above; this is set by OpenVINO setup

 - the environment's library path (e.g., `LD_LIBRARY_PATH` in Linux; this is also set by the OpenVINO
   setup scripts)
 - OpenVINO's default installation paths for the OS (a best effort attempt)
