Well, shoot. I feel dumb. I actually did that much on my own. Problem was I was also trying to follow the Particle docs on contributing the library and either those docs are bad or I did something wrong (seems maybe the latter). But either way, the resulting errors were somewhat overwhelming and looked like a further porting problem. I literally just decided to get back to simple and copy the .h and .cpp file from the library into my src directory and did the compile and it worked first shot.
So now I need to go back and try to work through the doc on contributing the library and see if I can make that part happen, too, I guess. I feel like there’s something not right about that “mylib” part of the docs, though.
