From af24f75c18c6a7900889ffd7a93f53715f18cdff Mon Sep 17 00:00:00 2001 From: liushuyu Date: Wed, 10 Feb 2021 22:18:25 -0700 Subject: [PATCH] externals: update httplib and libressl ... * In older `httplib`, SSL connections were not handled correctly and will have issues with proxy servers. Also, keep alive directives were not available back then, which is probably necessary to implement HTTP_C service correctly. * Another reason being `httplib` now requires OpenSSL 1.1+ API while LibreSSL 2.x provided OpenSSL 1.0 compatible API. * The bundled LibreSSL has been updated to 3.2.2 so it now provides OpenSSL 1.1 compatible API now. * Also the path hint has been added so that it will find the correct path to the CA certs on *nix systems. * An option is provided so that *nix system distributions/providers can use their own SSL implementations when compiling Yuzu/Citra to (hopefully) complies with their maintenance guidelines. * LURLParse is also removed since `httplib` can handle `scheme:host:port` string itself now. --- CMakeLists.txt | 2 +- externals/CMakeLists.txt
