All the existing plugins are set to #include from ../../sdk/include and build into $(SolutionDir)..\bin\$(Configuration)$(PlatformArchitecture)\plugins\ -
so that means you need to clone the plugins repository *under* the main ProcessHacker repository. Hopefully you'd be able to build smoothly then. If this still doesn't work - what is the exact build error you're seeing?
