Unable to install toolbox for new v140_clang_3_7 in Visual Studio 2015 Update 1 CMake

Question

So, I just downloaded the new Visual Studio Update 1 and am trying to get CMake to create the right set of platform tools.

New in Update 1 A new toolbox has appeared: Clang 3.7 with Microsoft CodeGen

Pretty interesting, yes!

Anyway, I'm trying to get CMake to generate the correct toolbox here.

Assumption 1: . The name of the toolbox that CMake will accept will be v140_clang_3_7. I guess this is because this is what is in brackets, and this is what is used in other toolboxes like v120etc.

So, I am setting up a simple test case:

C:\Users\russe\Documents\TestCMAKECLANG>ls
CMakeLists.txt  main.cpp

C:\Users\russe\Documents\TestCMAKECLANG>cat CMakeLists.txt
cmake_minimum_required(VERSION 3.0)


add_executable(TestEXE main.cpp)
C:\Users\russe\Documents\TestCMAKECLANG>cat main.cpp


// use some fancy c++14 feature that VS doesn't have

template<typename T>
constexpr T doThing{};

int main(){}
C:\Users\russe\Documents\TestCMAKECLANG>

CMake :

2:

C:\Users\russe\Documents\TestCMAKECLANG>cmake -G "Visual Studio 14 2015" -T "v140_clang_3_7"
