header, serializer, and proxy files\nfor every pipeline's mojom data definition file.\n\nSigned-off-by: Paul Elder \nReviewed-by: Laurent Pinchart \n\n---\nChanges in v4:\n- rename module_generated.h.tmpl to module_ipa_interface.h.tmpl\n- rename module_serializer.h.tmpl to module_ipa_serializer.h.tmpl\n- rename libcamera_generated headers to libcamera_generated_ipa_headers\n in meson\n\nChanges in v3:\n- change parser path to our wrapper parser script, instead of running\n mojo's directly\n\nChanges in v2:\n- clean up loops\n- remove non-literal keys in maps\n- move loading the mojom scripts to utils/\n- declare the template files in meson\n- add the generated headers into libcamera_generated_headers instead of\n libcamera_internal_headers\n- add libcamera_generated_headers to libcamera_sources\n---\n include/libcamera/ipa/meson.build | 78 +++++++++++++++++++\n src/libcamera/meson.build | 1 +\n src/libcamera/proxy/meson.build | 18 +++++\n
