[opus] Opus header includes

[Stéphane Letz]

Hi,

Why are the opus headers access described like this in the .pc file (located with pkg-config) :  Cflags: -I${includedir}/opus

This seems strange since instead of using something like :

#include <opus/opus.h> 
#include <opus/opus_types.h> 

developers have to use :

#include <opus.h>
#include <opus_types.h >

Seems like strange for me... Any reasons for that?

Thanks.
