      Consider building Qt WebEngine with Clang on Windows. Upstream Chromium switched to clang as default toolchain on Windows a while ago:

      http://blog.llvm.org/2018/03/clang-is-now-used-to-build-chrome-for.html

      (Upstream) Reasons given for the switch:

      • clang works better with distributed build systems
      • same toolchain for all platforms

      Drawbacks:

      • clang seems to be slower than MSVC
      • clang binaries are reportedly bigger
      • at time of writing, it still requires a full Visual Studio installation (uses VS headers + linker)

      Things to find out:

      • Which version of Clang is supported & where to get it?
      • Are Clang and MSVC binary compatible enough that we can mix a VS build of Qt with a Clang build of Qt WebEngine?
