Build error for Mega2560

Building NeoPixelTopologyTest failed for Mega2560 with fresh install of IDE and latest code from github.

Arduino : 1.8.19 (Windows 7), Carte : "Arduino Mega or Mega 2560, ATmega2560 (Mega 2560)"

          ^~~~~~~~~~~~

compilation terminated.

exit status 1

I didn't see any issue on this error and no prerequisites info on wiki & readme. Am I missing something ?

Not sure what changed, but the change is simple. In the ino, swap the order of includes too...

#include <NeoPixelBus.h>
#include <NeoPixelAnimator.h>

[furynick]

Build successful with swapped includes.

Almost all examples under topologies folder have the same issue.

Thanks for your help.
