Something along these lines *should* work:
gcc -DHAVE_CONFIG_H -Wall -Werror -g -O2 -shared -fPIC -Isrc/ -Isrc/daemon/ -ldl -o myplugin.so contrib/examples/myplugin.c
Although it seems there are a couple of issues with this myplugin.c example
(include paths are incorrect to start with).

For the "automatic" part to happen, the plugin needs to get declared in
configure.ac and src/Makefile.am, then the build.sh script ran. This will
generate the configure script, which itself will generate the Makefiles.
Take a look at a recent pull-request adding a new plugin on github.
https://github.com/collectd/collectd/pull/1805/files is a good example.
