LLVM 4.0 was built with MSVC 2017 toolset. I get linker errors regardless of
what toolset I use to build Mesa (MSVC 2015 or 2017). Building LLVM with MSVC
2015 toolset requires the whole Viual Studio 2015 because CMake uses Msbuild
tool which backward compatibility toolsets like MSVC 2015 toolset on MSVC 2017
don't have access to. With Mesa on the other hand using Scons which is an
alternative to Msbuild I can get away, by just using the toolset. I'd rather
wait for this to be fixed, then reinstalling Visual Studio 2015 to see if it
works, it was horribly bloated, forcing me to install .NET and Azure SDKs just
to tell everything is up-to-date although I never used them.

The log I posted in all attachments is from this script:
