Since you have compiled it I expect that it will work. But you must
provide a correct OpenSSL library as I already wrote.

If these are the only errors then I think that you have made progress,
because it seems that symbols which were missing before can now be found
by the linker.
But not all neccessary symbols. Which means that your OpenSSL library
files do not contain all functionality needed by libssh2.
Again, I recommend that you spend the time to learn to build OpenSSL
yourself, so that you can build an OpenSSL library which suits your
project.
This also allows you to later update OpenSSL in your final program
independently, which I consider very important when using a less
common platform (ie. ARMv4 Windows Mobile).
