We don't typically document all possible dependencies of packages in
the help text, it would be annoying to maintain. Handling them in
the .mk file is enough.

Why would the license change ? The license of libxmlsec1 itself remains
MIT.

I guess that openssl/gnutls/libgcrypt is actually a choice, i.e one
would use one of the three, correct ?

If so, then you can do:

	select BR2_PACKAGE_OPENSSL if !BR2_PACKAGE_GNUTLS && !BR2_PACKAGE_LIBGCRYPT

in the Config.in file, and:

ifeq ($(BR2_PACKAGE_OPENSSL),y)
LIBXMLSEC1_DEPENDENCIES += openssl
LIBXMLSEC1_CONF_OPTS += --with-openssl=$(STAGING_DIR)/usr
else ifeq ($(BR2_PACKAGE_GNUTLS),y)
...
else ifeq ($(BR2_PACKAGE_LIBGCRYPT),y)
...
endif

You could also do the same to support libxslt as an optional
dependency. All of this can be done as part of the initial libxmlsec1
submission, or as follow-up patches.

Best regards,

Thomas
