build: 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
therefore a check is required.

Check for WITH_MONOLITHIC_BUILD requirements added (prevents issue #724)
