WITH_SSL=bundled defined in cmake/ssl.cmake

# - "bundled" uses source code in <source dir>/extra/yassl
 
# - "system"  (typically) uses headers/libraries in /usr/lib and /usr/lib64
 
# - a custom installation of openssl can be used like this
 
#     - cmake -DCMAKE_PREFIX_PATH=</path/to/custom/openssl> -DWITH_SSL="system"
 
#   or
 
#     - cmake -DWITH_SSL=</path/to/custom/openssl>
 
#
 
# The default value for WITH_SSL is "bundled"

Comment by Marko Mäkelä [ 2020-05-22 ]

As far as I can tell, the test fails also on 10.1. It currently is the only 10.1 failure on Mac OS X. See http://buildbot.askmonty.org/buildbot/builders/mac-1012-bintar/builds/7203 for a recent example. That compilation appears to use a bundled SSL library.

10.1-bf74f7f9ff40f8a17e739e9ab6f5c906ccb9e892-WITH_SSL:STRING=bundled connects with TLS-1.1 which isn't supported by the server.

with newer ssl
openssl-devel.x86_64 1:1.1.1g-1.fc31

on 10.1 branch:
cmake -DWITH_SSL=system won't compile as it expects the old openssl API (OLD_OPENSSL_API fails)

Comment by Daniel Black [ 2020-06-19 ]

see MDEV-21881 for more detailed TLS/SSL compatibility per branch.
