<PackageName>_ROOT
------------------
Calls to :command:`find_package(<PackageName>)` will search in prefixes
specified by the ``<PackageName>_ROOT`` CMake variable, where
``<PackageName>`` is the name given to the ``find_package`` call
and ``_ROOT`` is literal. For example, ``find_package(Foo)`` will search
prefixes specified in the ``Foo_ROOT`` CMake variable (if set).
See policy :policy:`CMP0074`.
This variable may hold a single prefix or a
:ref:`;-list <CMake Language Lists>` of multiple prefixes.
See also the :envvar:`<PackageName>_ROOT` environment variable.
