[Qt-creator] Turn off "suggest-override" clang-tidy warning?

[Andy]

Thanks Eike.

The project is based on Qt 5.15.2. ClangCodeModel is on.

I have it set in the Analyzer prefs to "Analyze open files". Both
clang-tidy & clazy point to the executables in QtCreator.app.

When I run "clang-tidy & clazy" manually through the Debug tab, it shows:

warning: 'metaObject' overrides a member function but is not marked
'override' [suggest-override]
warning: 'qt_metacall' overrides a member function but is not marked
'override' [suggest-override]
warning: 'qt_metacast' overrides a member function but is not marked
'override' [suggest-override]

And the tooltip on them has the link from my first email.

But it doesn't show the warning inline in the editor on the Q_OBJECT line.
(I'm fairly sure it was showing those when I reported it? I don't know -
I'm sleep deprived.)

Adding "-Wno-suggest-override" to analyzer's Clang Warnings DOES fix it, so
thank you! Still don't understand where it's coming from though.

I'm also confused why we have Clang Warning "Diagnostic Configurations"
under both the "C++ -> Code Model" and  "Analyzer".
