Can't build on Windows

[andrewteta]

Using the master branch, I can't compile on Windows. Here's the output of CMake configure:

D:\Programs\MTD\ingenialink>cmake -H. -B_build -DCMAKE_INSTALL_PREFIX=%INSTALL% -DWITH_PROT_ETH=ON -DWITH_PROT_ECAT=ON

CMake Warning at cmake/StyleCheck.cmake:36 (message):

The output from CMake build is: log.txt

Should I expect this many warnings? Any idea how to resolve the errors (e.g. "Cannot open include file: 'iconv.h': No such file or directory")? Is there a specific compiler version I should use?
