[CMake] CPack and WIX: Preselected components

[Micha Renner]

With the NSIS generator I can create a dialog with a drop_down list
with two elements default and developer. Default is selected by default
when the dialog starts, so the default parts of the package are
installed. Selecting developer the devlop parts are installed and the
default files not. 

How can I do the same with the WiX generator?

With code below the WiX generator installs the complete package. 
What I want is that the user can selected the develop part if he wants
it.
