The SDK support provided in the workbench allows the developer to choose which of the installed SDKs to work with. From the chosen SDK, Symbian OS plug-ins pick-up information such as header files, import libraries, documentation and other SDK specific information.
You can add and manage SDKs in the Symbian SDKs panel. The Symbian SDKs preference panel lists all available SDKs and allows you to rescan system drives for newly installed and supported SDKs.
