I have visual studio 2015 (community) installed. It can compile C++ fine. Do I still need the Windows SDK to use mex, or is there a way for mex to work with my VS installation? It currently does not detect a compiler. Do I need to change an environment variable, or can I explicitly supply a path to mex with the compiler, e.g. C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\bin?
