From OpenSCADAWiki
OpenSCADA modules are enabled and disabled by passing the arguments configure --enable-{ModName} and configure --disable-{ModName} . When selecting modules, you can specify the policy "Enable all modules" — configure --enable-AllModuls or "Disable all modules" — configure --disable-AllModuls, and further enable-disable individual modules, whichever is easier. Most OpenSCADA modules can be linked (embedded) directly into the OpenSCADA core library, rather than being built as a separate library, for which the configure --enable-{ModName}=incl argument must be specified.
