| <PackageName>_ROOT |
| ------------------ |
| |
| .. versionadded:: 3.12 |
| |
| Calls to :command:`find_package(<PackageName>)` will search in prefixes |
| specified by the ``<PackageName>_ROOT`` CMake variable, where |
| ``<PackageName>`` is the (case-preserved) name given to the |
| :command:`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:`semicolon-separated list <CMake Language Lists>` of multiple prefixes. |
| |
| See also the :envvar:`<PackageName>_ROOT` environment variable. |
| |
| .. variable:: <PACKAGENAME>_ROOT |
| |
| .. versionadded:: 3.27 |
| |
| Calls to :command:`find_package(<PackageName>)` will also search in |
| prefixes specified by the upper-case ``<PACKAGENAME>_ROOT`` CMake |
| variable. See policy :policy:`CMP0144`. |
