CMake Visual Studio 2015 C compiler is unknown

I am trying to use cmake for the first time to compile an old c project with Visual Studio 2015 however I keep getting c compiler is unknown. The error from cmake is as following;

Compiling the C compiler identification source file "CMakeCCompilerId.c" failed.

The output was:

I have looked at these answers but not found a working solution.

Cmake Visual Studio 2015 Identification Unknown

CMake cannot identify C compiler from installed Visual Studio 2015

CMake does not find Visual C++ compiler

C compiler identification is unknown despite setting CC and CXX variables

The command I am using is 

cmake -G "Visual Studio 14 2015" .

I have tried both 3.6.0-rc3 and 3.5.2 versions of cmake.

I got rc.exe on my path by following instructions from this question.

Visual Studio can't build due to rc.exe

Any help would be greatly appreciated!

Go to MSVC setup from control panel, modify the installation and set this flag

(for me installing SDK from M$ website strangely didn't help)
