Hello everyone,  
When compiling the slicer code, I am getting an error. What could be the reason for it? Do I need to change the Cmake.lists file? I am extending a loadable module. Do I need SubjectHierarchyPlugins directory in my module? I went through some other loadable modules such as Models and Markups. They have the folder named SubjectHierarchyPlugins.

Any help would be much appreciated!

Best regards,  
Anish

Do you build latest master version and follow [these instructions](https://slicer.readthedocs.io/en/latest/developer_guide/build_instructions/linux.html)?

Did you have trouble building unmodified Slicer?  
You should not modify Slicer source code but add your custom modules in an extension.
