Replace -Wswitch-enum with -Wswitch, and add it into cmake rules too

Browse Source 
According to https://gcc.gnu.org/onlinedocs/gcc/Warning-Options.html:
  -Wswitch-enum
  Warn whenever a switch statement has an index of enumerated type and lacks a
  case for one or more of the named codes of that enumeration. case labels
  outside the enumeration range also provoke warnings when this option is used.
  The only difference between -Wswitch and this option is that this option
  gives a warning about an omitted enumeration code even if there is a *default
  label*.
