Description Greg Bedwell 2019-05-20 10:03:14 PDT 
Reported by a team here who are experimenting with building their codebase with clang-cl:

"""
The bug we observed is:

If you install the LLVM Compiler Toolchain Visual Studio extension for VS 2019 on a machine without VS 2017 (or without the VS 2017 extension), the LLVM platform toolset does not exist.

You can reproduce this by:

* Install the LLVM toolchain and VS 2019 extension on a machine without VS 2017, observe that the LLVM toolset does not appear as an option under Platform Toolset in the IDE.
* Install VS 2017, the LLVM toolset is still missing.
* Install the LLVM toolchain extension for VS 2017, the LLVM toolset now exists and works.

Sadly, there is nobody really maintaining the extension at this point.

The code is under llvm/tools/msbuild/ and patches are welcome.
