There are lots of man pages and example programs, but I'm not aware of
a tutorial as such.

You're missing the final step:

  sudo make install

Without that, your new libssh2 won't be usable.

The proper way to compile with libssh2 (once you've installed it) is to
use pkg-config to determine the correct compiler flags to use. Assuming
that you installed libssh2 into the default location (/usr/local/)
you'd use a command like this to compile:

env PKG_CONFIG_PATH=/usr/local/lib/pkgconfig \
gcc -Wall -g -O2 `pkg-config libssh2 --cflags --libs` -o main sftp_write.c
