- Removed dependency on cmake version 2.8.9
  Object libraries can now be created with dune_add_library(<target>
  OBJECT <sources>). It will create a GLOBAL property
  _DUNE_TARGET_OBJECTS:<target>_ that records the full path to the
  source files. Theses can later be referenced by providing
  _DUNE_TARGET_OBJECTS:<target>_ as one of the sources to dune_add_library

  dependency,  <basename>.pdf would be build in non-safe mode before
  install leading to errors with eps figures.

 documentation besides doxygen can be installed.
- Make sure we install under ${CMAKE_INSTALL_PREFIX}. Therefore
  we must provide the absolute path to our custom install script.
- Include DuneDoc at toplevel and let create the doc target. Thus
  we can use its macros all over the place.
