<PackageName>_ROOT
------------------
.. versionadded:: 3.12
.. include:: ENV_VAR.txt
Calls to :command:`find_package(<PackageName>)` will search in prefixes
specified by the ``<PackageName>_ROOT`` environment 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`` environment variable (if set). See policy :policy:`CMP0074`.
This variable may hold a single prefix or a list of prefixes separated
by ``:`` on UNIX or ``;`` on Windows (the same as the ``PATH`` environment
variable convention on those platforms).
See also the :variable:`<PackageName>_ROOT` CMake variable.
.. envvar:: <PACKAGENAME>_ROOT
.. versionadded:: 3.27
Calls to :command:`find_package(<PackageName>)` will also search in
prefixes specified by the upper-case ``<PACKAGENAME>_ROOT`` environment
variable. See policy :policy:`CMP0144`.
.. note::
Note that the ``<PackageName>_ROOT`` and ``<PACKAGENAME>_ROOT``
environment variables are distinct only on platforms that have
case-sensitive environments.
