CMake build system for Luvit 0.6.1
CMake provides convenient cross platform configuration/build system. You can still use gyp
or Makefiles to build luvit. Yet CMake is the only system now provided successefull builds
for Windows platform.

There are some examples:

1. Build luvit with clang on Linux:
       mkdir -p build/install
       mkdir -p build/cmake && cd build/cmake
       CC=clang CXX=clang++ cmake -DCMAKE_INSTALL_PREFIX=../install
-DCMAKE_BUILD_TYPE=Release ../..
       make install/strip

2. Build luvit with Visual Studio 2010/NMake on Windows:
       "%VS100COMNTOOLS%\vsvars32.bat"
       mkdir build\install
       mkdir build\cmake && cd build\cmake
       cmake -G "NMake Makefiles" -DCMAKE_BUILD_TYPE=Release
-DCMAKE_INSTALL_PREFIX=../install ..\..
       nmake install
