 `-Db_lto=true` activates link-time optimizations. `-Dcapabilities=enabled` enables the option that fastd can later negotiate capabilities with its peer accordingly. `-Doffload_l2tp=enabled` enables the option to later offload L2TP connections in fastd to the kernel and thus increase speed.
 
-In addition, the `-Doptimization=3` flag can be used to perform strong optimizations. The flag `-Dmethod_cipher-test=enabled` can be used to use the `cipher-test` method in fastd.
