Integration with Opal-RT's RT-LAB simulator can be enabled on Windows by installing RT-LAB 7.2.4. This allows vehicles to be simulated in RT-LAB and communicate directly with QGC on the same computer as if the UAS was actually deployed. This support is enabled by default once the requisite RT-LAB software is installed. Disabling this can be done by adding `DISABLE_RTLAB` to the `DEFINES` variable.
### Speech syntehsis
QGroundcontrol can notify the controller of information via speech synthesis. This requires the `flite` library on Linux. On Mac and Windows support is built in to the OS as of OS X 10.6 (Snow Leopard) and Windows Vista. This support is enabled by default on all platforms if the dependencies are met. Disabling this functionality can be done by adding `DISABLE_SPEECH` to the `DEFINES` variable.
