This automatically works because CMake's `if` statement considers variables which' content ends with "-NOTFOUND" to be FALSE. The previous version however was first tried as a variable which didn't exist. As a result after that it's interpreted as a string (not a variable anymore). So it skips the "-NOTFOUND" check and only does a "string not empty" check. Which, as this is a string constant, is always true.

Of course this only fixes the check. It doesn't address the fact that the remaining code below depends on
GIT_REVhaving some content. So maybe insteadfind_programshould be called with theREQUIREDflag?
