      Description

      Under terms of MDEV-5304 we upgraded PCRE to 8.34
      but did not add a CMake options to compile against an
      external PCRE library.
      We should eventually add a CMake option.

      The problem is that using an external PCRE is dangerous
      because of a possible stack overrun, which we fix in the bundled
      PCRE with the patch pcre/maria-patches/pcre_stack_guard.diff.

      There are some options:
      a. wait for the PCRE team to add some built-in means to watch the stack
      b. use the current PCRE version and check the pattern against
      nested parenthesis every time we call pcre_compile().
