Subject: [PATCH] Support CMake on Microsoft Windows

This is a working CMake based build system for Windows:

- While this should work with system wide installed libraries, it's
  still highly recommended to use the latest version of our official
  Windows build environment.
- It was tested with out official build environment on Windows 7 with
  32 bit and 64 bit builds
- You'll need something in the lines of this nice and short command:
    cmake -G Unix\ Makefiles \
     -DSDL2_LIBRARY=C:/MinGW/32/LIBS/lib/libSDL2.dll.a \
     -DSDL2_INCLUDE_DIR=C:/MinGW/32/LIBS/include \
     -DZLIB_INCLUDE_DIR=C:/MinGW/32/LIBS/include \
     -DZLIB_LIBRARY=C:/MinGW/32/LIBS/lib/libz.a \
     -DOGG_LIBRARY=C:/MinGW/32/LIBS/lib/libogg.dll.a \
     -DOGG_INCLUDE_DIR=C:/MinGW/32/LIBS/include \
     -DVORBIS_LIBRARY=C:/MinGW/32/LIBS/lib/libvorbis.dll.a \
     -DVORBIS_INCLUDE_DIR=C:/MinGW/32/LIBS/include \
     -DVORBISFILE_LIBRARY=C:/MinGW/32/LIBS/lib/libvorbisfile.dll.a \
     -DVORBISENC_LIBRARY=C:/libvorbisenc.dll.a \
     -DOPENAL_LIBRARY=C:/MinGW/32/LIBS/lib/libOpenAL32.dll.a \
     -DOPENAL_INCLUDE_DIR=C:/MinGW/32/LIBS/include ..
 Yes, forward slashes! Backslashes will break!
