Hi Matthias,
thanks for working on this, I also have a libcamera package here :) and
want to share a few findings.

Please see below about selecting the crypto lib. Than this would be
changed to:
select GNUTLS if LIBCAMERA_IPA_MODULE_SIGN_GNUTLS
select OPENSSL if LIBCAMERA_IPA_MODULE_SIGN_OPENSSL

I would provide the user the choice of selecting/enabling the ipa module
signing.
config LIBCAMERA_IPA_MODULE_SIGN
bool
default y
prompt "Enable IPA module signing"
help
Without IPA module signing, all IPA modules will be isolated in a
separate process. This adds an unnecessary extra overhead at runtime.
if LIBCAMERA_IPA_MODULE_SIGN
choice
prompt "Crypt provider"
default LIBCAMERA_IPA_MODULE_SIGN_GNUTLS
config LIBCAMERA_IPA_MODULE_SIGN_GNUTLS
bool "gnutls"
config LIBCAMERA_IPA_MODULE_SIGN_OPENSSL
bool "openssl (libcrypto)"
endchoice
endif

Marco
