CMAKE_FIND_USE_PACKAGE_REGISTRY

Controls the default behavior of the find_package() command for whether or not to search paths provided by the User Package Registry.

By default this variable is not set and the behavior will fall back to that determined by the deprecated CMAKE_FIND_PACKAGE_NO_PACKAGE_REGISTRY variable. If that is also not set, then find_package() will use the User Package Registry unless the NO_CMAKE_PACKAGE_REGISTRY option is provided.

This variable takes precedence over CMAKE_FIND_PACKAGE_NO_PACKAGE_REGISTRY when both are set.

In some cases, for example to locate only system wide installations, it is not desirable to use the User Package Registry when searching for packages. If the CMAKE_FIND_USE_PACKAGE_REGISTRY variable is FALSE, all the find_package() commands will skip the User Package Registry as if they were called with the NO_CMAKE_PACKAGE_REGISTRY argument.
