That indeed appears to be what happens.

I'm not familiar with xcode, so I assumed that if you install it would 
install all configurations, or you would specify which you want to install.

When I use the command line I use

 cmake --build . --target install --config Debug

so it is specified. 

So, I don't know what you mean here. Can you be more specific, keeping in 
mind I don't know xcode?

Assuming there is some unavoidable reason that the configuration is not 
known when installing, does that mean that frameworks which contain a foo 
and a foo_debug can not be created by cmake?

I left a comment on the original Qt bug above that he should look into using 
DYLD_IMAGE_SUFFIX. Is that right?

Thanks,

Steve.
