-I is for import directives only. imports are needed to compile the 
importing module. All other modules still need to be compiled themselves 
and added to the program either as individual .o files or as libraries 
(e.g. .a, .lib, etc.).

The method you've shown is a shorthand for "compile each to .o and add 
each to the program."

Working as expected... :)
