Okay, that's nice.
Just to say, even without auto
for (const std::string& item : lst) {
...
}
is easier to comprehend than
for (std::vector<std::string>::const_iterator it = lst.begin();
it != lst.end(); ++it) {
const std::string& item = *it;
...
}
which is as C++(98) as can be.

Very nice. C++11 was such a great improvement to the language.
It's much more fun to work with. Even with the slightly limited
feature set available in CMake.
