No, there is not.

Maybe you can write a macro which helps you with that. Like 
MY_ADD_EXECUTABLE(), which takes the same arguments as the normal 
ADD_EXECUTABLE(), but before handing them all over to ADD_EXECUTABLE(), check 
if each file exists and if it doesn't, create it using FILE(WRITE ...).
But then you may get problems with files generated via ADD_CUSTOM_COMMAND().
I would not recommend this.
