# FindRuby
# --------
#
# Find Ruby
#
# This module finds if Ruby is installed and determines where the
# include files and libraries are. Ruby 1.8 and 1.9 are supported.
#
# The minimum required version of Ruby can be specified using the
# standard syntax, e.g. find_package(Ruby 1.8)
#
# It also determines what the name of the library is. This code sets
# the following variables:
#
# ::
#
# 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_VERSION = the version of ruby which was found, e.g. "1.8.7"
# 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
