# This module defines the following variables utilizing
# git to determine the parent tag. And if found the macro
# will attempt to parse them in the github tag fomat
#
# 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=${EVENT_GIT___VERSION_PATCH}")
#    message("        stage=${EVENT_GIT___VERSION_STAGE}")
