CLion plugin

Hi,

I would create a CLion plugin for an embeded system.

I see in other projects the use of classes as CMakeProjectWizard, CMakeWorkspace, etc imported by a package 

com.jetbrains.cidr.cpp.cmake.workspace

but this package seems to be missing in the Intellij plugin sdk, also if the clion FAQ refers this project for build ua clion plugin.

So, how I can include these classes in my plugin ?
