Hi,
after finally having installed the corrent version of visual studio I'm stuck at building llvm/clang (step 6 of swift/WindowsBuild.md at main · apple/swift · GitHub)
The step where it failed:
FAILED: tools/clang/lib/Tooling/Refactor/CMakeFiles/clangToolingRefactor.dir/Extract.cpp.obj

[1934/2529] Building CXX object tools\clang\lib\Frontend\CMakeFiles\clangFrontend.dir\ASTConsumers.cpp.obj
ninja: build stopped: subcommand failed.
Apparently I have to set the /bigobj flag only I have no Idea where and how. All instructions I find are about the (Visual Studio) IDE.
Anyone who can help me with that?
