Specify which registry views must be queried. This option is only meaningful
|
|
on ``Windows`` platforms and will be ignored on other ones. When not
|
|
specified, the |FIND_XXX_REGISTRY_VIEW_DEFAULT| view is used when the
|
|
:policy:`CMP0134` policy is ``NEW``. Refer to :policy:`CMP0134` for the
|
|
default view when the policy is ``OLD``.
|
|
|
|
``64``
|
|
Query the 64-bit registry. On 32-bit Windows, it always returns the string
|
|
``/REGISTRY-NOTFOUND``.
|
|
|
|
``32``
|
|
Query the 32-bit registry.
|
|
|
|
``64_32``
|
|
Query both views (``64`` and ``32``) and generate a path for each.
|
|
|
|
``32_64``
|
|
Query both views (``32`` and ``64``) and generate a path for each.
|
|
|
|
``HOST``
|
|
Query the registry matching the architecture of the host: ``64`` on 64-bit
|
|
Windows and ``32`` on 32-bit Windows.
|
|
|
|
``TARGET``
|
|
Query the registry matching the architecture specified by the
|
|
:variable:`CMAKE_SIZEOF_VOID_P` variable. If not defined, fall back to
|
|
``HOST`` view.
|
|
|
|
``BOTH``
|
|
Query both views (``32`` and ``64``). The order depends on the following
|
|
rules: If the :variable:`CMAKE_SIZEOF_VOID_P` variable is defined, use the
|
|
following view depending on the content of this variable:
|
|
|
|
* ``8``: ``64_32``
|
|
* ``4``: ``32_64``
|
|
|
|
If the :variable:`CMAKE_SIZEOF_VOID_P` variable is not defined, rely on the
|
|
architecture of the host:
|
|
|
|
* 64-bit: ``64_32``
|
|
* 32-bit: ``32``
|
