FindRuby
--------
Find Ruby
This module finds if Ruby is installed and determines where the
include files and libraries are. Ruby 1.8 through 3.2 are
supported.
The minimum required version of Ruby can be specified using the
standard syntax, e.g.
.. code-block:: cmake
find_package(Ruby 2.5.1 EXACT REQUIRED)
# OR
find_package(Ruby 2.4)
It also determines what the name of the library is.
Virtual environments such as RVM are handled as well, by passing
the argument ``Ruby_FIND_VIRTUALENV``
Result Variables
^^^^^^^^^^^^^^^^
This module will set the following variables in your project:
``Ruby_FOUND``
set to true if ruby was found successfully
``Ruby_EXECUTABLE``
full path to the ruby binary
``Ruby_INCLUDE_DIRS``
include dirs to be used when using the ruby library
``Ruby_LIBRARIES``
.. versionadded:: 3.18
libraries needed to use ruby from C.
``Ruby_VERSION``
the version of ruby which was found, e.g. "1.8.7"
``Ruby_VERSION_MAJOR``
Ruby major version.
``Ruby_VERSION_MINOR``
Ruby minor version.
``Ruby_VERSION_PATCH``
Ruby patch version.
.. versionchanged:: 3.18
Previous versions of CMake used the ``RUBY_`` prefix for all variables.
The following variables are provided for compatibility reasons,
don't use them in new code:
``RUBY_EXECUTABLE``
same as Ruby_EXECUTABLE.
``RUBY_INCLUDE_DIRS``
same as Ruby_INCLUDE_DIRS.
``RUBY_INCLUDE_PATH``
same as Ruby_INCLUDE_DIRS.
``RUBY_LIBRARY``
same as Ruby_LIBRARY.
``RUBY_VERSION``
same as Ruby_VERSION.
``RUBY_FOUND``
same as Ruby_FOUND.
Hints
^^^^^
.. versionadded:: 3.18
``Ruby_FIND_VIRTUALENV``
This variable defines the handling of virtual environments managed by
``rvm``. It is meaningful only when a virtual environment
is active (i.e. the ``rvm`` script has been evaluated or at least the
``MY_RUBY_HOME`` environment variable is set).
The ``Ruby_FIND_VIRTUALENV`` variable can be set to empty or
one of the following:
* ``FIRST``: The virtual environment is used before any other standard
paths to look-up for the interpreter. This is the default.
* ``ONLY``: Only the virtual environment is used to look-up for the
interpreter.
* ``STANDARD``: The virtual environment is not used to look-up for the
interpreter (assuming it isn't still in the PATH...)
