For backward compatibility, the ``SUBVERSION_FOUND`` variable is also set to the same value. ``Subversion_VERSION`` .. versionadded:: 4.2 Version of the ``svn`` command-line client found. Cache Variables ^^^^^^^^^^^^^^^ The following cache variables may also be set: ``Subversion_SVN_EXECUTABLE`` Path to the ``svn`` command-line client. Commands ^^^^^^^^ This module provides the following commands if the Subversion command-line client is found: .. command:: Subversion_WC_INFO Extracts information from a Subversion working copy located at a specified directory: .. code-block:: cmake Subversion_WC_INFO( [IGNORE_SVN_FAILURE]) This command defines the following variables if running Subversion's ``info`` subcommand on ```` succeeds; otherwise a ``SEND_ERROR`` message is generated: ``_WC_URL`` URL of the repository (at ````). ``_WC_ROOT`` Root URL of the repository. ``_WC_REVISION`` Current revision. ``_WC_LAST_CHANGED_AUTHOR`` Author of last commit. ``_WC_LAST_CHANGED_DATE`` Date of last commit. ``_WC_LAST_CHANGED_REV`` Revision of last commit. ``_WC_INFO`` Output of the command ``svn info `` The options are: ``IGNORE_SVN_FAILURE`` .. versionadded:: 3.13 When specified, errors from Subversion operation will not trigger a ``SEND_ERROR`` message. In case of an error, the ``_*`` variables remain undefined. .. command:: Subversion_WC_LOG Retrieves the log message of the base revision of a Subversion working copy at a given location: .. code-block:: cmake Subversion_WC_LOG( ) This command defines the following variable if running Subversion's ``log`` subcommand on ```` succeeds; otherwise a ``SEND_ERROR`` message is generated: ``_LAST_CHANGED_LOG`` Last log of the base revision of a Subversion working copy located at ````. Deprecated Variables ^^^^^^^^^^^^^^^^^^^^ The following variables are provided for backward compatibility: ``Subversion_VERSION_SVN`` .. deprecated:: 4.2 Use the ``Subversion_VERSION``. Version of the ``svn`` command-line client found.
