> adding other features in API 2.0.
> The OpenVINO runtime wil be installed in /usr/local/, please add path

Installation paths are up to the system administrator and are detected
with pkg-config as per your patch, so this does not belong in the commit
message.

Headers should be grouped according to some principle, typically
per-library and alphabetically ordered.

This is a system header, it needs to use <>

asserts express internal code constraints, you must never assert on
outside data.

This file is schizophrenic about opening brace placement. It should
always be on its own line.

Same as above.
