[Exim] MySQL libraries

Hello again,

I actually managed to run successfully my make command to build exim supporting MySql.

In my Local/Makefile file, I put for the Mysql-related:
LOOKUP_MYSQL=yes
LOOKUP_INCLUDE=-I /usr/local/mysql/include
LOOKUP_LIBS=-I /usr/local/mysql/lib/mysql -lmysqlclient

make and make install are fine.
But when I try to run exim (i.E. exim -bV), I get the following error:

error in loading shared libraries: libmysqlclient.so.6: cannot open shared object file: No such file or directory

Help will be appreciated
Guillaume
