+AddUninstallTarget
+------------------
+
+Add the "uninstall" target for your project::
+
+  include(AddUninstallTarget)
+
+
+will create a file ``cmake_uninstall.cmake`` in the build directory and add a
+custom target ``uninstall`` (or ``UNINSTALL`` on Visual Studio and Xcode) that
+will remove the files installed by your package (using
+``install_manifest.txt``).
+See also
+https://gitlab.kitware.com/cmake/community/wikis/FAQ#can-i-do-make-uninstall-with-cmake
+
+The :module:`AddUninstallTarget` module must be included in your main
+``CMakeLists.txt``. If included in a subdirectory it does nothing.
+This allows you to use it safely in your main ``CMakeLists.txt`` and include
+your project using ``add_subdirectory`` (for example when using it with
+:cmake:module:`FetchContent`).
+
+If the ``uninstall`` target already exists, the module does nothing.
