How to build wxWidgets for Windows

For sure we need Visual Studio installed (get the community edition for free).  After we install the source code package (e.g, in B:\WxWidgets-3.0.4)

Steps to build:

1. Open "x64 Native Tools Command Prompt for VS ..." Command shell (just type in the Cortana search)
2. Change to the wxWidgets directory
3. type: 

b:
cd wxWidgets-3.0.4\build\msw
nmake /f makefile.vc

After it finishes, just set WXWIN environment variable to poin to that directory (e.g, B:\WxWidgets-3.0.4)
