Hello.  
i am following the tutorial of skeletal representation ([SrepModule-Tutorial\_v5.0 - Google Slides](https://docs.google.com/presentation/d/1BF5Y4wAXOAS2yfdrmJeujrZFiKsnh9GwOs-XgQg8RZE/present?slide=id.p1)). But there is SkeletalRepresentationRefiner in the tutorial:

I’ve tried another way to install the SkeletalRepresentationRefiner module via github. But when i built the s-rep extension using command cmake, the error occurred.

So i can not install the extension via souce code.  
Can someone help me please?

Hi Dyatsen,

The s-rep extension is not yet shipped in Slicer binary. I suggest you build it from its source.

I assume there is no Slicer built in your machine. This page: [Documentation/Nightly/Developers/Build Instructions - Slicer Wiki](https://www.slicer.org/wiki/Documentation/Nightly/Developers/Build_Instructions) will help you in building Slicer. Note the versions of software required.

After building Slicer, you need to configure the Slicer\_DIR for the extension. Overall, the extension relies on Slicer. Building it with CMAKE is analogous to building your projects in windows with Visual studio: for example, if project A uses libraries provided by project B, you need compile and bulid project B first and then add it into your build configurations for project A.

Hope this helps.
