Addon sources don’t show up in the Project Navigator within Xcode

[timolden]

After generating a project with the project generator including the addon, the OF related source files don’t show up in the Project Navigator within Xcode.

This is a minor issue because the project will build fine, but it is often convenient to have the source files available in the Navigator for quick reference.

It is these six source files that don’t show up:

ADDON_SOURCES += $(OF_ROOT)/libs/openFrameworks/video/ofGstUtils.h
ADDON_SOURCES += $(OF_ROOT)/libs/openFrameworks/video/ofGstUtils.cpp
ADDON_SOURCES += $(OF_ROOT)/libs/openFrameworks/video/ofGstVideoPlayer.h
ADDON_SOURCES += $(OF_ROOT)/libs/openFrameworks/video/ofGstVideoPlayer.cpp
ADDON_SOURCES += $(OF_ROOT)/libs/openFrameworks/video/ofGstVideoGrabber.h
ADDON_SOURCES += $(OF_ROOT)/libs/openFrameworks/video/ofGstVideoGrabber.cpp

(Have seen this behavior in Xcode 7 & 8 and OF 0.9.n & 0.10.1)

Manually adding them will result in errors, as the project does already has them included.
