In that example, it will look in the directory of the calling template. The
"component" part of the call tells it that you're creating an object of type
"component." You can also have a mapping to a directory for components, and
you can also use dot notation.
For example:
<cfset myAdder = createObject("component", "addsTwoNumbers") />
looks in current directory or looks in mapped cfc directory if it's at
the root (but I doubt that)
<cfset myAdder = createObject("component", "cfc.addsTwoNumbers") />
looks in root of directory mapped to /cfc
