Using a simple command line like:

mosquitto_pub -d  -m '{"foo": "bar"}' -L mqtts:https://my-server:1234/foo

I would expect that the command line client tries to establish a connection using TLS, using the system wide CAs. Like curl, "HTTPie", …

However, mosquitto_pub silently uses non-TLS, which (in the best case) would simply fail:

Client mosq-XWCkqLXiT8HblH1vWQ sending CONNECT
Error: The connection was lost.

You can use --capath /etc/ssl/certs to activate TLS mode with the system CAs, but I agree that using mqtts:https:// should do this by default.

Also, the path is different on all platforms.

@ralight
Add lib and client support for OS CA certs
29c771c 
- Add `MOSQ_OPT_TLS_USE_OS_CERTS` option, to instruct the client to load and  trust OS provided CA certificates for use with TLS connections.
- All clients now load OS provided CA certificates if used with `-L
  mqtts:https://...`, or if port is set to 8883 and no other CA certificates are
  used. Closes #1824.
- Add the `--tls-use-os-certs` option to all clients.

Closes #1824. Thanks to Jens Reimann.
