| |
| :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. |
