Build succeed and work well with OF 0.9.2 & 0.9.3. But Failed on OF 0.9.6. Still can not find the cause.

But I have found two latest issues about setColor and getColor:

1. ofPixels::getColor(int index) is broken.  openframeworks/openFrameworks#5321
2. ofPixels::getColor(int index) is broken.  openframeworks/openFrameworks#5321

Problem fixed in OF 0.9.7
