Extend commit eb35d8884b (find_package: Use PackageName_ROOT variables
as search prefixes, 2018-03-15, v3.12.0-rc1~349^2) to also check
upper-case `<PACKAGENAME>_ROOT` variables. Add policy `CMP0144` to
enable the behavior in a compatible way.
Fixes: #24403

<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.

.. 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`.
