Then, I described it poorly.  :)

It will find the first of any of the named things in the PATH.  This 
assumes all names are equally desirable, and if what ever the first one 
found is good enough.

find_program(foo NAMES fooalias1 fooalias2 fooaliase3)

This will find the first fooalias in the PATH.

What you want is for it to find fooalias1 even if there is a fooalias3 
higher in the PATH.  That is not what it does... :)
