Headers which must not be exposed as part of the public libcamera API should include base/private.h. Any interface which includes the private.h header will only be able to build if the libcamera_private dependency is used (or the libcamera_base_private dependency directly). Build targets which are intended to use the private API's will use the libcamera_private to handle the automatic definition of the inclusion guard.
