Operating system: Ubuntu 22.04  
Slicer version: 5.3.0  
Expected behavior: After successfully building custom extension with conan cmake, I expect my modified OpenIGTLinkIF module to show up in modules.  
Actual behavior: However, after building my modified version of SlicerOpenIGTLink and its OpenIGTLinkIF module, it doesn’t show up in 3D Slicer.

Has anyone built a custom extension with conan cmake? Any help or guidance would be greatly appreciated as I am aiming to use 3D slicer for my master thesis on AI stroke diagnosis.

The conan option sounds interesting, but I don’t know that anyone has used it before. Best to stick with the documented toolchain to make sure things are working, and then try out new tools

@pieper since I need to use conan for my project, I could create a tutorial or document how to do it when I get it working and share it with the Slicer Community. Any suggestions on contributing to 3D Slicer?

It would be great if you could make such a contribution. Probably a PR to add info to [the extension instructions](https://slicer.readthedocs.io/en/latest/developer_guide/extensions.html) would be good. I’m not familiar with conan, but it sounds like something we might be able to use other places as well.

Can you write a bit more about conan? What are the advantages compared to simply using CMake? What makes it required for you to use conan?
