It does what the documentation says (enable). Bill's answer
was incorrect unless he was referring to something else. There
are three cases:
- User passes -DCMAKE_BIULD_TYPE on the command line and gets a warning
because it is misspelled and therefore unused. This is ON by default
but can be disabled with --no-warn-unused-cli, or by *gasp* not passing
unused variables.
- Project does ${UNINITIALIZED_VAR} and nothing happens, but it can
be a warning if --warn-uninitialized is passed. This is intended to
help cleanup project source code.
- Project does set(VAR_THAT_IS_NOT_USED 1) and nothing happens, but
can be a warning if --warn-unused-vars is passed.
