+#         add the correct HG revision, use only +hgX without number.
 #
 # IMPORTANT: If you modify the file, cmake re-creates the version header. But
 #            it is not able to set all library version. Please re-run cmake if
 #            you change something here.

 # NOTE: do not add a space after #. The current CMake script will fail.
