Building OpenCV Visual Studio 14 2015 Unicode Errors

I am trying to build OpenCV with Visual Studio 2015 and am unable to do so. This was done by pulling the git repository. Nothing fancy here, no CUDA, no contrib, etc. This is something I have done multiple times in the past but this time I am getting weird unicode conversion errors such as:

opencv-master\modules\core\src\glob.cpp(117): error C2664: 'BOOL FindNextFileA(HANDLE,LPWIN32_FIND_DATAA)': cannot convert argument 2 from 'WIN32_FIND_DATA *' to 'LPWIN32_FIND_DATAA'

and

opencv-master\modules\videoio\src\cap_vfw.cpp(165): error C2664: 'HRESULT AVIFileOpenW(PAVIFILE *,LPCWSTR,UINT,LPCLSID)': cannot convert argument 2 from 'const char *' to 'LPCWSTR'

I have turned CV_ENABLE_INTRINSICS off in the cmake configuration as this seems to be a problem at the moment.

So why build OpenCV when I can just download the binaries you say... Well I was trying to compile with CUDA and the contrib libraries, but I had these same problems...

Anyone know the answer here? This is a new install of Visual Studio 2015, so this definitely could be me at fault.

Edit: I do realise the git version is 3.3
