Aurora INO. sketch w/SmartMatrix/SmartMatrixSD/Teensy

Has anyone figured out how to get the Aurora sketch running onto their SmartMatrix (Hub75) board?
I keep getting this error even though SmartMatrix_32x32.h file IS located where it needs to be.

/Volumes/EXTERNAL HD/Arduino/Sketchbook/Teensy32x32MatrixSlideshow-main/aurora-1.6.2/Aurora/Aurora.ino:30:31: fatal error: SmartMatrix_32x32.h: No such file or directory
compilation terminated.
Error compiling for board Teensy 3.2 / 3.1.

Managing libraries isn’t any help as it’s not listed among the .h files within my libraries folder I have already installed.
