icon.h issue

[PickleRick55]

When trying to compile the firmware I keep running into the same issue. It tells me that the icon.h file doesn't exist or that there is no such file. I followed the instructions on this website and included the file in the same location as the Orbion_FW_v0.26.3.ino file, but am still getting the error message. I have enclose a picture of both the error message and the files that I am storing. I am also making the older model which is why I am running Arduino. Any help would be apricated.
Thanks,
