#
# This CMake code extracts the information from the git repository,
# and automatically causes a reconfigure if the git HEAD changes. The
# following variable may be defined after execution:
#
# _GIT_VERSION_HASH - the SHA1 hash of the current HEAD
#
# Based on the most recent tag starting with the letter "v" for
# version, which is expected to be of the form
# vN.N[.N[.N][(a|b|c|rc[N])] the following is extracted or undefined:
#
# _GIT_VERSION_MAJOR
# _GIT_VERSION_MINOR
# _GIT_VERSION_PATCH
# _GIT_VERSION_TWEAK
# _GIT_VERSION_RC
#
# If the current project's version ( defiend by
# ${CMAKE_PROJECT_NAME}_VERSION_MAJOR and MINOR and PATCH and TWEAK
# match that of the tag, then it'll be considered that the project is
# in post release mode otherwise it's considered underdevelopment.
#
# Only one of the following variables will be defined.
# _GIT_VERSION_DEV is defined as number of commits
# since the projects Version.cmake file has been modified. While
# _GIT_VERSION_POST is defined as the number of commits since the tag.
