<PackageName>_ROOT
|
|
------------------
|
|
|
|
Calls to :command:`find_package(<PackageName>)` will search in prefixes
|
|
specified by the ``<PackageName>_ROOT`` CMake variable, where
|
|
``<PackageName>`` is the name given to the ``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:`;-list <CMake Language Lists>` of multiple prefixes.
|
|
|
|
See also the :envvar:`<PackageName>_ROOT` environment variable.
