I've bumped the required Qt version to 5.2.0, which is what the dev branch 
happens to identify itself as currently.

The real problem here is one of expectations. Therefore, you might have 
similar issues in the future.

For the sake of future proofing, I suggest you adjust your expections as 
follows:

1) If you can't build frameworks, and it is possible to update your Qt 
build, then update your Qt build. Don't expect to get an error at cmake 
time.
2) If you update your Qt repos, do a clean build and a clean install. Don't 
expect a dirty build to work.

opposite of the above, though I don't know why.

Thanks,

Steve.
