Which Header Files Should I Include?

For a typical application, add [sdkroot]/Framework as an include folder, then add:

Vulkan

#include "PVRShell/PVRShell.h"
#include "PVRUtils/PVRUtilsVk.h" //Includes everything, including PVRVk

OpenGL ES

#include "PVRShell/PVRShell.h"
#include "PVRUtils/PVRUtilsGles.h"

If PVRCamera is required

#include PVRCamera/PVRCamera.h
