| .. 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. | |
