Locally built client: Error creating SSL context

Development
#1

Hello,
I've just started working on the client. I've been able to build the client in Qt. The projects runs , but on trying to sync , I get an error message in the GUI based client and owncloudcmd. The user client installed does not show this error . This is the error message I get in owncloud cmd:

I think this is an issue with some SSL dlls missing. I appreciate if anyone who's faced this issue can help .
Thanks for your help!

I figured out why this happens. For windows use v1.01 and not v1.1 from slproweb.com/

Thanks

@kaustubh hm. Actually, linking against SSL should not be needed to build the client if you are working in master branch (i.e. after https://github.com/owncloud/client/pull/5833). Build docs should be adapted to be consistent.

Hi,
I'm working on a fork 13 days old. I'll pull the changes and then work on it.

Thanks

Also make sure to follow the Qt instructions regarding OpenSSL.
