Right, I didn't think about LLVM. To be honest, I have no clue on its
actual usage and compatibility with Qt so I can't really comment on this.

I only mentioned build-essential because qt-sdk (which is the
highest-level meta-package in the lot) does depend on it :
$ apt-cache depends qt-sdk
qt-sdk
Depends: build-essential
<snip>
I can see your point though. I'm no packager so I can't tell why qt-sdk
depends on build-essential rather than individual packages (excluding
dpkg-dev which is not needed as you pointed it out).
Maybe there could also be some enhancement to be made there?

Couldn't agree more. ;)
However, some users expect that installing qtcreator will give them a
fully functioning environment, and won't install qt-sdk because they
don't even know about it.
To be frank, the reason why I bumped this bug is because the issue arose
on a French Debian forum, and I couldn't immediately figure out the
cause of the problem because, like you, I assumed that a C++ compiler
would be installed.
As the affected user put it: "how strange is it that eg. gnome-core
recommends brasero while qtcreator won't work out of the box?"
To me this situation seemed to be against the Debian spirit to do the
right thing from the start, hence my initial proposal to put the whole
qt-sdk as a Recommends for qtcreator.
But again I'm no packager, just another Debian user so I lack some
important insight for sure.

Since g++ is sufficient for QtCreator to be able to recognize the Qt
libraries, this looks like a winner to me.
cmake is not installed by qtcreator either, but this is only for non-Qt
projects so I guess it's not very relevant as far as qtcreator is concerned.
Again, thanks for your involvement in making Debian even better. :)
