A linux instruction is attached. I've also attached my AMBuildScript.7z to the thread. If you build a release version (not debug) remove this: '-Wno-error' from it. There are some bad mistakes in the extension that can't be ignored. This line: -stdlib=libstdc++' forces the compiler to build the extension statically with libstdc, it may not be necessary.
For windows use this:

Start/Пуск -> Settings (Optional)-> Control Panel/Панель управление -> System/Система -> Advanced/Дополнительные параметры системы -> Environment Variables/Параметры среды

ADD:
HL2SDKCSS C:\...\...\hl2sdk-css
MMSOURCE C:\...\...\mmsource
SOURCEMOD C:\...\...\sourcemod-central

Then replace the variables here: msvc10/sdk.vcxproj

And I'm afraid it may be difficult to build the windows version against the recent source sdk
