dnl Test for mysql availability using mysql_config

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)
