[mgerhardy]

mkdir override
cd override
cmake -DTB_BUILD_DEMO=OFF -DCMAKE_CXX_CLANG_TIDY:STRING="clang-tidy-4.0;-checks=modernize-use-override;-fix" ..
cmake --build .

used clang-tidy

Why is it that it wants override in these cases, and not in all the other hundreds of places i override virtual methods?

updated the pr manually. For me there are no warnings for -Winconsistent-missing-override when including turbobadger headers in my project. But it is possible that there are still warnings left if you compile turbobadger itself (I'm using different compiler flags for external code).

Looks like the tb namespace fix made it into this pr.. it should not be a problem because it's in master anyway already - if it is, let me know, then I will rebase this again.
