| 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 |
