-------
.. versionadded:: 3.12
:command:`find_package` uses ``<PackageName>_ROOT`` variables.
In CMake 3.12 and above the :command:`find_package(<PackageName>)` command now
searches prefixes specified by the :variable:`<PackageName>_ROOT` CMake
variable and the :envvar:`<PackageName>_ROOT` environment variable.
Package roots are maintained as a stack so nested calls to all ``find_*``
commands inside find modules and config packages also search the roots as
prefixes. This policy provides compatibility with projects that have not been
updated to avoid using ``<PackageName>_ROOT`` variables for other purposes.
The ``OLD`` behavior for this policy is to ignore ``<PackageName>_ROOT``
variables. The ``NEW`` behavior for this policy is to use
``<PackageName>_ROOT`` variables.
