# FindGit
# -------
#
#
#
# The module defines the following variables:
#
# ::
#
# GIT_EXECUTABLE - path to git command line client
# GIT_FOUND - true if the command line client was found
# GIT_VERSION_STRING - the version of git found (since CMake 2.8.8)
#
# Example usage:
#
# ::
#
# find_package(Git)
# if(GIT_FOUND)
# message("git found: ${GIT_EXECUTABLE}")
# endif()
