Cross platfrom code to OS functions

Based on sample code from example code for the Intel IPP library

To build use

	./build.sh configure
   	./build.sh build

it will:

  configure
    create directories ./build/debug and ./build/release
    run cmake with release and debug with CMAKE_BUILD_TYPE
  build
    just run make file for both debug and release

-- Release -- You can also run in order to compile only release version

    ./build.sh configure
    ./build.sh release

--Debug -- Or run, to compile only debug wersion

    ./build.sh configure
    ./build.sh debug

-- Clean-- After the job done, be sure to clean up the mess:

./build.sh clean

(it removes all files and subdirectories from ./build directory)

CMAKE is used to bring native compilation envirenments for different platforms

e.g.: We use QTCreater to debug. It is easy to import cmake project to it. Just use "open project" in file menu, select global project's CMakeLists.txt. Set arguments -DCMAKE_BUILD_TYPE=Debug -DCMAKE_INSTALL_PREFIX=./build/debug and you are ready.

For other IDE use cmake-gui to generate eg.: VS2010 project.
