Except Graphviz's `dot` Doxygen may use few other utilities like `mscgen` (Message Sequence Chart) and `dia` (Diagram Editor). Now this module allows to manage Doxygen settings from `CMakeLists.txt` and forget about `Doxyfile`s. Also it provides a helper function to add a target to generate documentation: `doxygen_add_docs`. Implement code review notes: - Introduce `COMPONENTS` to find: `dot`, `mscgen` and `dia`; - Deprecate variables `DOXYGEN_SKIP_DOT`, `DOXYGEN_EXECUTABLE`, `DOXYGEN_DOT_EXECUTABLE`, `DOXYGEN_DOT_FOUND` in favour of `doxygen_add_docs ` usage instead; - Properly handle paths to found tools in Windows; - Prevent adding a custom target if Doxygen was not really found; - Introduce exported (executable) targets for found components.
