CMake: fix dylib versioning

Browse Source 
match the behavior of autoconf in generating the -compatibility_version
and -current_version options. these use current + 1 and revision:
  # Darwin ld doesn't like 0 for these options...
  func_arith $current + 1
  minor_current=$func_arith_result
  ...
  verstring="-compatibility_version $minor_current -current_version $minor_current.$revision"

this requires CMake >= 3.17 to set the MACHO_COMPATIBILITY_VERSION and
MACHO_CURRENT_VERSION properties:
https://cmake.org/cmake/help/latest/prop_tgt/MACHO_COMPATIBILITY_VERSION.html

based on the fix in libexpat:
