CMAKE_FIND_PACKAGE_NO_SYSTEM_PACKAGE_REGISTRY — CMake 3.12.0 Documentation

# CMAKE_FIND_PACKAGE_NO_SYSTEM_PACKAGE_REGISTRY

Skip System Package Registry in `find_package()` calls.

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 enabled, all the `find_package()` commands will skip the System Package Registry as if they were called with the `NO_CMAKE_SYSTEM_PACKAGE_REGISTRY` argument.
