- improve compilation by removing the git sha1 dependency into its
own include file that is just used 2 times instead of auto.h that
is included in more places.
- moved configuration stuff from src to top level cmake file
- building static library task and using it for building task binary
- the static library will then be used as well in the unit tests
- added library checks to cmake
- added configuration of include files to cmake
- move package information into configurable include file
- cmake.h.in generates auto.h to be compatible with current
implementation of autoconf
