Installing Platform Toolset v120 under Visual Studio 2015

Question

With Visual Studio 2015 trying to build a C/C++ project that needs Platform Toolsets v120.
The required platform toolsets are not getting populated:

From this stackoverflow post it sounds as if it will not be possible to do so without installing Visual Studio 2013 on the same system. Is it really true ?

If so then what is the use of the build tools hosted by Microsoft ?

Answer 1

The build tool page says that the build tool is only for VB/C#.

"Build Tools 2013 provides the essential tools for building managed applications."

The v120 MSBuild folder (C:\Program Files (x86)\MSBuild\12.0\Bin) contains VB/C# compiler (vbc.exe, csc.exe), but it doesn't contains C++ compiler (cl.exe).

The cl.exe is located at "C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\bin\".
