                 CXXFLAGS='-DLIBMYSQLCLIENT_SONAME=\"$(shell readlink -f `mysql_config --variable=pkglibdir`/libmysqlclient_r.so | sed -e s/mysqlclient/mysqlclient_r/ | sed -e "s,`mysql_config --variable=pkglibdir`/\(libmysqlclient_r.so.[0-9][0-9]\).*,\\1,")\" $(CXXFLAGS)' \

from debian/rules. I didn't succeed in getting this into cmake. But this at least works...
