Porting MM:S plugins and SM Extensions to CS:GO
 

The sample plugin/extension msvc10 project files and Makefiles have recently been updated in mmsource-central and sourcemod-central, including the addition of configurations for building for CS:GO.

Also check out the MM:S Dev Wiki to see the Porting to Swarm and CS:GO article, and additionally the Porting to Left 4 Dead article first if you're coming up from CS:S or an earlier engine.

The CS:GO sdk can be found here.

Anything outside of the public/ dir, aside from cusercmd and ctakedamageinfo are unlikely to have been reversed, but it should be plenty for plugins. Feel free to request more.
