+ECMUninstallTarget
+------------------
+
+Add an ``uninstall`` target.
+
+By including this module, an ``uninstall`` target will be added to your CMake
+project. This will remove all files installed (or updated) by a previous
+invocation of the ``install`` target. It will not remove files created or
+modified by an ``install(SCRIPT)`` or ``install(CODE)`` command; you should
+create a custom uninstallation target for these and use ``add_dependency`` to
+make the ``uninstall`` target depend on it:
+
+.. code-block:: cmake
+
+  include(ECMUninstallTarget)
+  install(SCRIPT install-foo.cmake)
+  add_custom_target(uninstall_foo COMMAND ${CMAKE_COMMAND} -P uninstall-foo.cmake)
+  add_dependency(uninstall uninstall_foo)
+
+The target will fail if the ``install`` target has not yet been run (so it is
+not possible to run CMake on the project and then immediately run the
+``uninstall`` target).
+
+.. warning::
+
+  CMake deliberately does not provide an ``uninstall`` target by default on
+  the basis that such a target has the potential to remove important files
+  from a user's computer. Use with caution.
+
+Since 1.7.0.
