dnl @synopsis MYSQL_API_LOCATION
dnl
dnl This macro tries to find MySQL C API header and library locations.
dnl
dnl We define the following configure script flags:
dnl
dnl --with-mysql: Give prefix for both library and headers, and try
dnl to guess subdirectory names for each. (e.g. Tack /lib and
dnl /include onto given dir name, and other common schemes.)
dnl --with-mysql-lib: Similar to --with-mysql, but for library only.
dnl --with-mysql-include: Similar to --with-mysql, but for headers
dnl only.
