While commit 64a555d6f5aafed504a10e5b756e85c91b1d56ce was merged into
the master branch of https://github.com/libssh2/libssh2 there hasn't
been a release since then.

Try building current master and using that in your application.
I guess it will just work<tm>.

Note that building from git is different from building a release
tarball. You'll need the development infrastructure required by the
libssh2 source code; something like autotools or perhaps cmake.

We can't really educate you on building the git source, but look
around and you'll find this documented for lots of different projects
and the process is similar for libssh2.

One important thing to care about and get right in the source build
(whether git source build or release tarball build) is the particular
backend you choose for crypto operations. You'll want to choose one
that supports rsa2 operation - at the moment that seems to be
OpenSSL, mbedTLS and WinCNG.
