How to use Clang compiler with MSBuild?

Question

I\'m trying to take a couple of projects normally compiled on Windows with Microsoft C++ and compile them with clang instead.

On the upside, there exists clang-cl.ex

This is easy to do from either command line or project file. The properties you need to configure are $(CLToolExe) and $(CLToolPath).

From the command line:

msbuild MyProj.vcxproj /p:CLToolExe=clang-cl.exe /p:CLToolPath=c:\whatever\path\to\the\tool

Alternatively, inside your .vcxproj file:

  clang-cl.exe
  c:\whatever\path\to\the\tool

If you are calling task CL directly inside your .vcxproj file, as opposed to just relying on common targets, just set corresponding parameters ToolExe and ToolPath of the CL task.
