Title: Add central file to check for cmake requirements 

CMake allows to define variables (e.g. -D) even if they are not defined as options.
If a build feature requires a cmake version > 2.6 build might fail. In that case a check is required for oder versions.

Added checks for:

- WITH_MONOLITHIC_BUILD (prevents issue #724)
- Warning for GetGitRevisionDescription with cmake <= 2.8.2
