Suppress warnings for external headers in VS2017 Code Analysis

Question

I want to use the Code Analysis in Visual Studio 2017 but I\'m using Qt and it gives me a lot of warnings from the headers. I\'ve tried turning off warnings:

Answer 1

If you open your .vcxproj file, down the bottom you should see:

  <Import Project="$(VCTargetsPath)\Microsoft.Cpp.targets" />
  <ImportGroup Label="ExtensionTargets">
  </ImportGroup>

below this you can add:

  <PropertyGroup Condition="'$(Language)'=='C++'">
    <IncludePath>$(QTDIR)\include;.\GeneratedFiles;$(IncludePath)</IncludePath>
    <CAExcludePath>$(QTDIR)\include;.\GeneratedFiles;$(CAExcludePath)</CAExcludePath>
  </PropertyGroup>

Microsoft say there's a bug where CAExcludePath is overwritten by IncludePath but this is fixed in Visual Studio 2017 V15.3 and you'll only need to set CAExcludePath - I haven't verified this (I'll update this once I do).
