Currently, there is only compile support for Windows CE 5.0 Standard SDK for SH-4.
There is currently no "out of the box" support for the Windows CE Automotive or Portable Media SDKs from Microsoft.
Device manufacturers may prefer to make their own customized version of Windows CE using Platform Builder. In order for Qt for Windows CE to support a custom SDK, a build specification needs to be created. More information on Windows CE Customization can be found here.
