title: How to disable clang-cl specific warnings in VS project
body: <p>I use a 3rd party project, that produces huge amount of warnings. I disable all of them in VS project properties. Sometimes, I switch to <code>LLVM clang-cl</code> toolset to check for warnings from clang. The 3rd party project produces so many warnings with clang-cl that VS is chocking with the amount of output.
  I know how to disable them, I do so through command line args, for example: <code>Wno-int-conversion -Wno-shift-op-parentheses</code> etc. The problem, however, when I switch back to VS toolset, all of these command line params to disable warnings from clang-cl become errors (unknown cmd line args) with MS compiler.</p>
  
  <p>Is there a way to have both clang and VS settings in the same VS project? Maybe, somehow conditional on ClangCL toolset these could be added only for clang-cl builds?</p>
