Then you use 'PATTERN "${my_vcs_dir}" EXCLUDE' instead.

This is a bad practice because then CMake has no way to know if there
are new header files and can't regenerate/install correctly. Ok maybe a
new header coming in will happen to trigger a rerun of CMake because the
header happens to belong to one of your built libraries or executables,
but I think this solution is more dangerous than just excluding .svn
explicitly.
