Cacti Spine: configure: error: MySQL libraries not found

I was trying to compile the cacti spine poller source code and I encounter this error:
configure: error: MySQL libraries not found

root@V-NMS:/var/www/cacti-spine-0.8.7i# find / -name libmysqlclient.so
/usr/lib/i386-linux-gnu/libmysqlclient.so

To specify the lib location:
LDFLAGS="-L/usr/lib -L/usr/lib/i386-linux-gnu/" ./configure
