<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 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.
