dnl SYNOPSIS
dnl MYSQL_CHECK_SSL
dnl
dnl Provides the following configure options:
dnl --with-ssl=DIR
dnl Possible DIR values are:
dnl - no - the macro will disable use of ssl
dnl - bundled, empty or not specified - means use ssl lib
dnl bundled along with MySQL sources
dnl - ssl location prefix - given location prefix, the macro expects
dnl to find the header files in $prefix/include/, and libraries in
dnl $prefix/lib. If headers or libraries weren't found at $prefix, the
dnl macro bails out with error.
