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.
