There is a pseudo-URL you can add as a comment in code that will link to the Arduino Library Manager and search for a library.
#include "SparkFun_TMF882X_Library.h" //http://librarymanager/All#SparkFun_Qwiic_TMF882X
This way if somebody has your code they can click on the link and be taken straight to an install option within the Arduino IDE.
This is a really nice little usability feature I had no idea existed.I'll gloss over the fact Sparkfun originally typo-ed the link in the sketch in question. :-)
