Extended Description

If you install vcpkg from here: https://github.com/Microsoft/vcpkg

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);$(VcpkgRoot)debug\lib*.lib

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.
