+dnl Test for mysql availability using mysql_config
+dnl Uses --with-mysql= yes(autodetection - default) | no | path
+dnl Sets 4 variables:
+dnl   with_mysql = path/to/mysql_config (if found and can compile mysqlclient) or "no"
+dnl   np_mysql_include = flags for include, from mysql_config --include (will be guessed as $with_mysql/include if --include not found)
+dnl   np_mysql_libs    = flags for libs,    from mysql_config --libs
+dnl   np_mysql_cflags  = flags for cflags,  from mysql_config --cflags
+dnl Also sets in config.h:
+dnl   HAVE_MYSQLCLIENT
+dnl Copile your code with:
+dnl   $(CC) $(np_mysql_include) code.c $(np_mysql_libs)
