CMAKE_FIND_USE_SYSTEM_PACKAGE_REGISTRY
|
|
--------------------------------------
|
|
|
|
Controls searching the :ref:`System Package Registry` by the
|
|
:command:`find_package` command.
|
|
|
|
By default this variable is not set and the behavior will fall back
|
|
to that determined by the deprecated
|
|
:variable:`CMAKE_FIND_PACKAGE_NO_SYSTEM_PACKAGE_REGISTRY` variable.
|
|
If that is also not set, then :command:`find_package()` will use the
|
|
:ref:`System Package Registry` unless the ``NO_CMAKE_SYSTEM_PACKAGE_REGISTRY``
|
|
option is provided.
|
|
|
|
This variable takes precedence over
|
|
:variable:`CMAKE_FIND_PACKAGE_NO_SYSTEM_PACKAGE_REGISTRY` when both are set.
|
|
|
|
In some cases, for example to locate only user specific installations, it
|
|
is not desirable to use the :ref:`System Package Registry` when searching
|
|
for packages. If the ``CMAKE_FIND_USE_SYSTEM_PACKAGE_REGISTRY``
|
|
variable is ``FALSE``, all the :command:`find_package` commands will skip
|
|
the :ref:`System Package Registry` as if they were called with the
|
|
``NO_CMAKE_SYSTEM_PACKAGE_REGISTRY`` argument.
|
|
|
|

and :variable:`CMAKE_FIND_USE_PACKAGE_ROOT_PATH` variables.
