You can then enable them again with one of the CAPSTONE_<ARCH>_SUPPORT options.

By default, all architectures are compiled in. If you're building a static library that you intend to link into
multiple consumers, and they have differing architecture requirements, you may want -DCAPSTONE_USE_ARCH_REGISTRATION=1
and call cs_arch_register_*() for the architectures you need in each particular consumer. In this way you only pay
footprint size for the the architectures you're actually using in each consumer, without having to compile Capstone
multiple times.

Besides, Capstone also allows some more customization via following macros.
