It seems that certain extensions reliably fail to build on Mac due to missing svn command. For example SlicerRT or SlicerHeart:

[https://slicer.cdash.org/viewBuildError.php?buildid=2323746](https://slicer.cdash.org/viewBuildError.php?buildid=2323746)  
[https://slicer.cdash.org/viewBuildError.php?buildid=2323865](https://slicer.cdash.org/viewBuildError.php?buildid=2323865)

The source code of these extensions does not seem to contain anything SVN related. The only common thing is that both are superbuild extensions, but none of the built subprojects have SVN repositories.

Any ideas how to fix the Mac factory build for these extensions? Thanks!

There are 2 factory macOS build machines (factory-south-macOS.kitware and computron-macOS-tests.kitware).

See [Mac factory error - "svn: error: Failed to locate 'svn'." - #4 by lassoan](https://discourse.slicer.org/t/mac-factory-error-svn-error-failed-to-locate-svn/16938/4)

Thanks. Sorry, should have done a search.

Help finalizing this PR that removes SVN support would be great:
