[BUILD] add CMake targets to build binary and source packages with CPack

This patch adds the following CMake targets

  - package
  - source

to build bundeled packages. Those packages contain either all built
binary artifacts or all source files for source code distribution. Both
CMake targets are available in Release build configuration.
