Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Introducing FFSM2 and HFSM2 state machine libraries
Here is a gist showing a 3 level hierarchy using sml. https://gist.github.com/indiosmo/08ab24181770125d5a2448d27f6ae99f. Comparing the two, esp. when anything related to *hierarchical* state machines are involved, I strongly prefer HFSM2. Even when comparing the source code, I prefer HFSM2 https://github.com/andrew-gresyk/HFSM2/blob/master/include/hfsm2/machine.hpp to boost::sml https://github.com/boost-ext/sml/blob/master/include/boost/sml.hpp.

State machine library for portable embedded application (C++11)
Me and my team faced a similar issue since we often port code between different OS and frameworks (embedded automotive). Unfortunately, I couldn't find anything which fully satisfied our requirements so ended up creating an HSM library myself. You can see it on GitHub and check if it suits your needs: https://github.com/igor-krechetov/hsmcpp
