# FindGit
# -------
#
# The module defines the following variables:
#
# ``GIT_EXECUTABLE``
# Path to Git command-line client.
# ``Git_FOUND``, ``GIT_FOUND``
# True if the Git command-line client was found.
# ``GIT_VERSION_STRING``
# The version of Git found.
#
# Example usage:
#
# .. code-block:: cmake
#
# find_package(Git)
# if(Git_FOUND)
# message("Git found: ${GIT_EXECUTABLE}")
# endif()
