dnl @synopsis MYSQL_C_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 by tacking common
dnl suffixes on like /lib and /include.
dnl --with-mysql-lib: Same as --with-mysql, but for library only.
dnl --with-mysql-include: Same as --with-mysql, but for headers only.
