Including the `CTest` modules ensures that the `BUILD_TESTING` option is
defined and automatically calls `enable_testing()` if needed. It does not
change the default or introduce any dependencies on its own.

Sandbox2 is a C++ security sandbox for Linux which can be used to run untrusted
programs or portions of programs in confined environments. The idea is that the
runtime environment is so restricted that security bugs such as buffer overflows
in the protected region cause no harm.
