New in version 3.1.
Deprecated since version 3.16: Use the CMAKE_FIND_USE_SYSTEM_PACKAGE_REGISTRY variable instead.
By default this variable is not set. If neither CMAKE_FIND_USE_SYSTEM_PACKAGE_REGISTRY nor CMAKE_FIND_PACKAGE_NO_SYSTEM_PACKAGE_REGISTRY is set, then find_package() will use the System Package Registry unless the NO_CMAKE_SYSTEM_PACKAGE_REGISTRY option is provided.
CMAKE_FIND_PACKAGE_NO_SYSTEM_PACKAGE_REGISTRY is ignored if CMAKE_FIND_USE_SYSTEM_PACKAGE_REGISTRY is set.
In some cases, it is not desirable to use the System Package Registry when searching for packages. If the CMAKE_FIND_PACKAGE_NO_SYSTEM_PACKAGE_REGISTRY variable is TRUE, all the find_package() commands will skip the System Package Registry as if they were called with the NO_CMAKE_SYSTEM_PACKAGE_REGISTRY argument.
