To build a plugin that is statically compiled into the server (assuming that the plugin supports static build), add -DWITH_<PLUGIN>=1 to the CMake command line.
To exclude a plugin from the build, use -DWITHOUT_<PLUGIN>=1
If neither WITH_<PLUGIN> nor WITHOUT_<PLUGIN> are defined, the plugin will be built as a shared module, if plugin supports it. If the plugin does not support build as a shared module, it won't be built.
WITH_PLUGIN_<PLUGIN> and WITH_<PLUGIN>_STORAGE_ENGINE are also supported.
