# GitVersion.cmake - Generate version information using information from git.
# Best suited with git-flow workflows.
# Written for building dcled-hidapi - userland driver for the Dream Cheeky LED Message Board
# Copyright 2018 Jahn Fuchs <github.jahnf@wolke7.net>
# Distributed under the MIT License. See accompanying LICENSE file.
# Definition:
# LAST_TAG_VERSION = latest tagged version (e.g. 1.2.0 for v1.2.0) or 0.0.0 if it does not exist.
#
# Version Number rules:
# - on 'master': X.Y.Z[-DIST] (using LAST_TAG_VERSION),while DIST should always be 0 on the master branch
# - on 'develop' and other branches : X.Y.Z-ALPHA_FLAG.DIST (using LAST_TAG_VERSION, incrementing Y by 1)
# - on release branches: X.Y.Z-RC_FLAG.DIST (using semver from release branch name
# or XYZ like on develop if not possible)
# DIST is either calculated to last tag or to the closest rc-X.Y.Z tag
# * DISTANCE is only added on versions from master branch when != 0
# * On all other branches DISTANCE is always added.
# * All version numbers besides the ones from master have a pre-release identifier set.
# * When printing the version string and the PATCH number is 0 - the patch number is omitted.
### Configuration
set(VERSION_TAG_PREFIX v) # Should be the same as configured in git-flow
set(VERSION_ALPHA_FLAG alpha) # Pre-release identifier for all builds besides release and hotfix branches
set(VERSION_RC_FLAG rc) # Pre-release identifier for all builds from release and hotfix branches
set(VERSION_RC_START_TAG_PREFIX "rc-") # If available tags with the given prefix are used for distance calculation on release branches.
set(RC_BRANCH_PREFIX release) # e.g. release/0.2
set(HOTFIX_BRANCH_PREFIX hotfix) # e.g. hotfix/2.0.3
set(MAIN_BRANCH master)
set(_GitVersion_DIRECTORY "${CMAKE_CURRENT_LIST_DIR}")

# ${prefix}_VERSION_SUCCESS // 0 on error (e.g. git not found), 1 on success

# - ${prefix}_OR_VERSION_MINOR
# - ${prefix}_OR_VERSION_PATCH
#
# A version 'type' (release or develop) in case the branch cannot be determined via git
