As far as I know this is not supported as a feature, but there may be 
ways to do it.  One easy way is just to add a library with a dummy 
source file and then list all the headers.  As long as nothing links to 
it it shouldn't affect anything.  There might also be a way using 
ADD_CUSTOM_TARGET, but I don't know off the top of my head how it might 
work.

You can add this as a feature request:

thought it probably won't be implemented for a while.
