Bug #1: Addition of a CMake build specification

This contribution added a build specification in the format that can be
processed by the tool "CMake".
http://cmake.org/

My approach is usable to some degree. I would appreciate your comments
for improvements.

I imagine that more fine-tuning for portability details would be nice.

Bug #2: Addition of support for the CPack installation system

The build specification was extended in the way that package archives and
component-based software installers can be generated by the cooperation of
the tools "CMake" and "CPack".
