To provide Windows-compatible functionality, spack code should use llnl.util.symlink instead of os.symlink. On non-Windows platforms and on Windows where supported, os.symlink will still be used. Use junctions when symlinks aren't supported on Windows (#22583) Support islink for junctions (#24182) Windows: Update llnl/util/filesystem * Use '/' as path separator on Windows. * Recognizing that Windows paths start with '<Letter>:/' instead of '/' Co-authored-by: lou.lawrence@kitware.com <lou.lawrence@kitware.com> Co-authored-by: John Parent <john.parent@kitware.com>
