+FindGit
+-------
+
+The module defines the following ``IMPORTED`` targets (when
+:prop_gbl:`CMAKE_ROLE` is ``PROJECT``):
+
+``Git::Git``
+  Executable of the Git command-line client.
+
+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()
