# This module defines the following variables utilizing

#
# Usful for auto-versionin in ou CMakeLists
#
# EVENT_GIT___VERSION_FOUND - Version variables foud
# EVENT_GIT___VERSION_MAJOR - Major version.
# EVENT_GIT___VERSION_MINOR - Minor version
# EVENT_GIT___VERSION_STAGE - Stage version
#
# Example usage:
#
# event_fuzzy_version_from_git()
# if (EVENT_GIT___VERSION_FOUND)
# message("Libvent major=${EVENT_GIT___VERSION_MAJOR}")
# message(" minor=${EVENT_GIT___VERSION_MINOR}")
# message(" patch=${EVENT_GIT___VERSION_PATCH}")
