Heinz Wiesinger 751ebe44fd Add feature summary at the end of cmake.
This gives a short overview over found/missing dependencies as well
as enabled/disabled features.

Initial author Heinz Wiesinger <heinz@m2mobi.com>

* Report all plugins enabled via MYSQL_ADD_PLUGIN
* Simplify code. Eliminate duplication by making use of WITH_xxx
  variable values to set feature "ON" / "OFF" state.
