[CMake] running FIND_PROGRAM twice

[David Cole]

And from the middle of the same text:
    is created to store the result of this command.  If the program is
    found the result is stored in the variable and the search will not be
    repeated unless the variable is cleared.  If nothing is found, the
    result will be <VAR>-NOTFOUND, and the search will be attempted again
    the next time FIND_PROGRAM is invoked with the same variable.  The

Score: pretty-clear 2 / not-so-clear 0
