My understanding is that:
- libcamera_base is everything in base
- libcamera_base_private is libcamera_base + the macro required for
using the private headers
- libcamera_dep is public + private, for things like IPAs and internal
components (but doesn't include the macro for private headers)
- libcamera_private is libcamera_dep + the macro
Kieran, is this correct? (it is a bit hard to keep track of...)
