Hello,
I have confirmed that my (and several other) extensions are not built with the build system. I have set up my own build machine, and several extensions are not cloned, and my build log has entries for configuration (of all extensions in the extension index), but nothing for building/testing/etc. (of a few extensions). There is nothing in the build log explaining why they aren’t built (that I could find via search).
Opening up SlicerExtensions.sln and building the extension (via Project SlicerVASST->Build Only This Project) results in a successful build of the extension.

I will continue investigating, but if anyone has any ideas, it would be much appreciated.
Cheers,
Adam
