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.
.. versionadded:: 3.14
The module defines the following ``IMPORTED`` targets (when
:prop_gbl:`CMAKE_ROLE` is ``PROJECT``):
``Git::Git``
Executable of the Git command-line client.
Example usage:
.. code-block:: cmake
find_package(Git)
if(Git_FOUND)
message("Git found: ${GIT_EXECUTABLE}")
endif()

# in the MSYS shell.
