In CMakeList.txt there is a case sensitivity issue which a fix was posted by Robert Osfield in the users forum. I also had to rename the files OSXAvFoundationCoreVideoTexture.h and OSXAvFoundationCoreVideoTexture.cpp to OSXAVFoundationCoreVideoTexture.h and OSXAVFoundationCoreVideoTexture.cpp Finally in OSXAvFoundationCoreVideoTexture.cpp the include OSXAVFoundationVideo.H was updated to OSXAVFoundationVideo.h"
