Modified CMake scripts to link against correct version of LLVM VISUAL_STUDIO_VERSION must be defined to either 2005 or 2008 when CMake is run. See build.bat for example usage.

@ECHO OFF
mkdir build_vs2008_miniegl
cd build_vs2008_miniegl
cmake -DUSE_MINI_EGL:Bool=ON %* -G "Visual Studio 9 2008" ..
cd ..
