Yes, I found that in my search. It's linked in the commit message of the Qt 
review request I linked to.

What surprises me is that in the time since ActiveQt and CMake could be used 
together, no one else has written such macros. 

Or has everyone using the ActiveQt modules written such macros separately? 

Or is it more likely that people using ActiveQt have manually done the post-
build steps, such as -dumpidl and creating the IDL type libbrary, outside of 
CMake?

I'm trying to find out how people use ActiveQt/CMake in practice in the real 
world, what compatibility needs to be kept, and if the CMake files generated 
for Qt 5 are useful at all, or need to be extended before becoming useful. 

Your reply makes me think that the Qt5 patch is useful to the same extent as 
the FindQt4 patch was useful - that it is enough that people can do the rest 
themselves (outside of CMake if needed)? Can you confirm?

Thanks,

Steve.
