How do you include Arduino.h when using mex to compile C code?

Write the Hardware-Specific C/C++ Code

I'm trying to follow the tutorial above but when I attempt to use mex I get the error below.

 Error using mex
 /home/USERNAME/Documents/Source/digitalio_arduino.cpp:1:21: fatal error: Arduino.h: No
 such file or directory
 compilation terminated.

What do I have to do to get Arduino.h to mex?

I'm using Ubuntu 16.04.

When set up mex the include directory is defined; need to put the file wherever that is on your system.

You may specify the header file path with MEX using the -I option. See this post:
