Currently, when building all apps via MITK_BUILD_ALL_APPS the resulting installer will be called MITK-Diffusion-2011(...) as defined in
CPackOptionsDiffusion.cmake
instead of MITK-2012.02.99_(...) as defined in
mitkSetupVariables.cmake
Ideally, if only one app is build, the installer should take the name from that one, if two or more are build (or the ALL_APPS option is checked) a default name should be used.
