| |
| :command:`find_package` uses upper-case ``<PACKAGENAME>_ROOT`` variables. |
| |
| In CMake 3.27 and above the :command:`find_package(<PackageName>)` command now |
| searches prefixes specified by the upper-case :variable:`<PACKAGENAME>_ROOT` |
| CMake variable and the :envvar:`<PACKAGENAME>_ROOT` environment variable |
| in addition to the case-preserved :variable:`<PackageName>_ROOT` and |
| :envvar:`<PackageName>_ROOT` variables used since policy :policy:`CMP0074`. |
| 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 if the original ``<PackageName>`` has lower-case characters. |
| The ``NEW`` behavior for this policy is to use ``<PACKAGENAME>_ROOT`` |
| variables. |
| |
| This policy was introduced in CMake version 3.27. CMake version |
| |release| warns when the policy is not set and uses ``OLD`` behavior. |
| Use the :command:`cmake_policy` command to set it to ``OLD`` or ``NEW`` |
| explicitly. |
