# FindRuby

Find Ruby

This module finds if Ruby is installed and determines where the include files and libraries are. Ruby 1.8, 1.9, 2.0 and 2.1 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

Also:

`RUBY_INCLUDE_PATH`
  same as RUBY_INCLUDE_DIRS, only provided for compatibility reasons, don’t use it
