In all cases the ``<name>`` is treated as case-insensitive and corresponds
to any of the names specified (``<package>`` or names given by ``NAMES``).
Paths with ``lib/<arch>`` are enabled if the
:variable:`CMAKE_LIBRARY_ARCHITECTURE` variable is set. If ``PATH_SUFFIXES``
is specified the suffixes are appended to each (W) or (U) directory entry
one-by-one.
:variable:`CMAKE_LIBRARY_ARCHITECTURE` variable is set. ``lib*`` includes one
or more of the values ``lib64``, ``lib32``, ``libx32`` or ``lib`` (searched in
that order).
* Paths with ``lib64`` are searched on 64 bit platforms if the
:prop_gbl:`FIND_LIBRARY_USE_LIB64_PATHS` property is set to ``TRUE``.
* Paths with ``lib32`` are searched on 32 bit platforms if the
:prop_gbl:`FIND_LIBRARY_USE_LIB32_PATHS` property is set to ``TRUE``.
* Paths with ``libx32`` are searched on platforms using the x32 ABI
if the :prop_gbl:`FIND_LIBRARY_USE_LIBX32_PATHS` property is set to ``TRUE``.
* The ``lib`` path is always searched.
If ``PATH_SUFFIXES`` is specified, the suffixes are appended to each
(W) or (U) directory entry one-by-one.
This set of directories is intended to work in cooperation with
projects that provide configuration files in their installation trees.
