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 :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).

This variable may hold a single prefix or a
|
|
|
|
|
:ref:`semicolon-separated list <CMake Language Lists>` of multiple prefixes.
