Option De-duplication
^^^^^^^^^^^^^^^^^^^^^
The final set of options used for a target is constructed by
accumulating options from the current target and the usage requirements of
its dependencies. The set of options is de-duplicated to avoid repetition.
.. versionadded:: 3.12
While beneficial for individual options, the de-duplication step can break
up option groups. For example, ``-option A -option B`` becomes
``-option A B``. One may specify a group of options using shell-like
quoting along with a ``SHELL:`` prefix. The ``SHELL:`` prefix is dropped,
and the rest of the option string is parsed using the
:command:`separate_arguments` ``UNIX_COMMAND`` mode. For example,
``"SHELL:-option A" "SHELL:-option B"`` becomes ``-option A -option B``.
