Add support for --with-openssl=PATH and --without-openssl, --with-curl=PATH and --without-curl, --with-expat=PATH and --without-expat ./configure options, each setting or unsetting appropriate NO_PACKAGE and if called with argument also PACKAGEDIR (of which only CURLDIR is documented in Makefile) All above options are supported as override to autodetection; more to come in the same style (override to autodetection), so moved the bulk of comments for site configuration down. Needs review by someone well versed in autoconf and m4. Signed-off-by: Jakub Narebski <jnareb@gmail.com> Signed-off-by: Junio C Hamano <junkio@cox.net>
