I think you want to remove the references to GLUT from the CoreOF.xcconfig file ( libs/openFrameworksCompiled/project/osx/CoreOF.xcconfig )
Remove this line:
LIB_GLUT = "$(OF_PATH)/libs/glut/lib/osx/GLUT.framework/Versions/A/GLUT"
And also remove this line from the run script build phase of your app:
# Copy GLUT framework (must remove for AppStore submissions)
rsync -aved ../../../libs/glut/lib/osx/GLUT.framework "$TARGET_BUILD_DIR/$PRODUCT_NAME.app/Contents/Frameworks/"
You might also want to remove these files from the openFrameworks Xcode project.
ofAppGlutWindow.cpp / .h
I hope that helps!
