0006 ECMUninstallTarget
0007 ------------------
0008 
0009 Add an ``uninstall`` target.
0010 
0011 By including this module, an ``uninstall`` target will be added to your CMake
0012 project. This will remove all files installed (or updated) by a previous
0013 invocation of the ``install`` target. It will not remove files created or
0014 modified by an ``install(SCRIPT)`` or ``install(CODE)`` command; you should
0015 create a custom uninstallation target for these and use ``add_dependency`` to
0016 make the ``uninstall`` target depend on it:
0017 
0018 .. code-block:: cmake
0019 
0020   include(ECMUninstallTarget)
0021   install(SCRIPT install-foo.cmake)
0022   add_custom_target(uninstall_foo COMMAND ${CMAKE_COMMAND} -P uninstall-foo.cmake)
0023   add_dependency(uninstall uninstall_foo)
0024 
0025 The target will fail if the ``install`` target has not yet been run (so it is
0026 not possible to run CMake on the project and then immediately run the
0027 ``uninstall`` target).
0028 
0029 .. warning::
0030 
0031   CMake deliberately does not provide an ``uninstall`` target by default on
0032   the basis that such a target has the potential to remove important files
0033   from a user's computer. Use with caution.
0034 
0035 Since 1.7.0.
