# 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.
