[CMake] Is there any ongoing work to support toolset Clang 3.7 with Microsoft CodeGen (v140_clang_3_7)

Hi,

Microsoft has released a new toolset using clang for the code analysis 
and with VS2015 code generator.

IS there any ongoing work to support the v140_clang_3_7 for VS2015 ?
Something like:

> cmake -G "Visual Studio 14 2015" -T v140_clang_3_7

For the moment if I want to test I have to use the VS2015 generator and 
then manually change the Platform Toolset and warnings level


Thanks
