As you can see from the responses, an analysis on CMake and iOS has been 
done, with encouraging results. These results, on conjunction with the 
results in the other platforms/configurations, gave us - some TqTC and 
KDAB devs - enough confidence that we think that we can pull it off. I 
did not ask you to join to make it happen, please don't put words into 
my mouth. I said that if you'd like to see something implemented before 
we get to it, then you're invited to join the effort.
