Thinking about it, I think that "required" should be set to
"get_option(enable_docs)", since if someone explicitly enables the docs
they should be built and cause error if they can't be.

Suggestion: add a run_target in an else leg to just print out "no
doxygen found" or similar message when ninja doc is called.
