        <pre>If you install vcpkg from here: <a href="https://github.com/Microsoft/vcpkg">https://github.com/Microsoft/vcpkg</a>

And run `vcpkg integrate install` from a command prompt, then the LLVM VS
integration stops working with this error message:

C:\src\vcpkg\installed\x64...\lib\*.lib: invalid argument error.

The error seems to be coming from this file:

c:\src\vcpkg\scripts\buildsystems\msbuild\vcpkg.targets

<AdditionalDependencies Condition="'$(VcpkgNormalizedConfiguration)' == 'Debug'
and '$(VcpkgAutoLink)' !=
'false'">%(AdditionalDependencies);$(VcpkgRoot)debug\lib\*.lib</AdditionalDependencies>

If you set the MSBuild project output verbosity to diagnostic level and get the
lld-link.exe command line it's running and then paste that into a command
prompt, it appears to work, so this appears to be an MSBuild issue.  But
perhaps there's a workaround we can submit in lld, or alternatively maybe we
can fix MSBuild and/or vcpkg.

This was reported by user henrik@ on IRC.</pre>
