Hi TK11,
as soon as i have time i will try to resolve the error. Seems recompiling oder linking SDL doesn´t work.
Next week i hope to have the time for that. Maybe late sunday.

edit:
Ok missing sdl.h was the error. When you use this plugins only in editor you only have to compile once. If you want to deploy your project recompiling is needed (obviously). In my instruction i advise to delete the sdl after compiling -> this is not correct 
My solution is to change the batch file slightly to get ready for compling sdl from source and NOT delete the sources after compiling. If you not have installed mercurial and/or cmake (x86) it will fail. The batchfile only checks for x86 cmake. With these changes the demo project deploys without errors on win x64.
