# - 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 # 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_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
