major improvement of FindRuby.cmake
-now supports specifying minimum required version -now supports ruby 1.8 and 1.9 -uses find_package_handle_standard_args() now -fix #6212 and using a lot of ideas from the file attached there Alex

# - Find Ruby
# This module finds if Ruby is installed and determines where the include files
-# and libraries are. It also determines what the name of the library is. This
+# and libraries are. Ruby 1.8 and 1.9 are supported. The minimum required version
+# specified in the find_package() command is honored.
+# It also determines what the name of the library is. This
# code sets the following variables:
#
-# RUBY_INCLUDE_PATH = path to where ruby.h can be found
# RUBY_EXECUTABLE = full path to the ruby binary
+# RUBY_INCLUDE_DIRS = include dirs to be used when using the ruby library
# RUBY_LIBRARY = full path to the ruby library
+# RUBY_FOUND = set to true if ruby ws found successfully
+#
+# RUBY_INCLUDE_PATH = same as RUBY_INCLUDE_DIRS, only provided for compatibility reasons, don't use it
