This macro checks for Ruby and tries to get the include path to ’ruby.h’. It provides the $(RUBY_CPPFLAGS) and $(RUBY_LDFLAGS) output variables. It also exports $(RUBY_EXTRA_LIBS) for embedding Ruby in your code.

You can search for some particular version of Ruby by passing a parameter to this macro, for example "2.2.1".
