Hi Daniel,
Sorry for not responding sooner. I've updated the project page with
example code for version 0.3 of the plugin:
http://code.google.com/p/cmake-maven-project/
This version only works under Windows and assumes that you installed
cmake yourself. I am actively working on version 2.8.7-b2 which will
bundle cmake 2.8.7 (so you don't have to install it yourself) and will
also support Linux.
