[Buildroot] Libcurl : to depend or not to depend ?

Hello,

> After my issue last week with libcurl it seems that libcurl uses openssl if it has been found. (if it was build before libcurl)
> If its not found then libcurl simply has no SSL support.

libcurl already has the following code:

ifeq ($(BR2_PACKAGE_OPENSSL),y)
LIBCURL_DEPENDENCIES += openssl
LIBCURL_CONF_ENV += ac_cv_lib_crypto_CRYPTO_lock=yes
# configure adds the cross openssl dir to LD_LIBRARY_PATH which screws up
# native stuff during the rest of configure when target == host.
# Fix it by setting LD_LIBRARY_PATH to something sensible so those libs
# are found first.
LIBCURL_CONF_ENV += LD_LIBRARY_PATH=$$LD_LIBRARY_PATH:/lib:/usr/lib
LIBCURL_CONF_OPT += --with-ssl=$(STAGING_DIR)/usr --with-random=/dev/urandom
else
LIBCURL_CONF_OPT += --without-ssl
endif

Which means that:

 * If the OpenSSL package is selected, then we guarantee that it is
   build *before* libcurl, and libcurl is built with OpenSSL support.

 * If the OpenSSL package is not selected, then we force libcurl to be
   compiled without SSL support

It doesn't work for you?
