missing libssh2-devel

I installed a red hat enterprise linux 7.2 and have the developer subscription. I am able to see the libssh2 from yum, but can't see the libssh2-devel.
How can I install the libssh2-devel package?

I can see this is update on this website: https://rhn.redhat.com/errata/RHSA-2016-0428.html
