Qt Creator 4.3.0 autocomplete won't suggest C++11 (worked in 4.2.1)
I have a project that was created with 'Import existing project'. In Qt Creator 4.2.1, the autocomplete for C++11 members/classes was working OK (e.g. std::unique_ptr), but it's no longer working in Qt Creator 4.3.0.
If I try to create a new project (e.g. a C++ library) in Qt Creator 4.3.0, then C++11 autocomplete somehow works, but I have no idea what makes it work or how to apply the same setting to my original project.
Platform: Ubuntu Linux 16.04 x86_64
