A few hints:
1. Currently there is no way to link DSO files against other libraries. A
patch is available (and was posted to new-httpd by me recently) but no
release version still contains support for this. So as an implication you
_CANNOT_ use --enable-shared=auth_mysql.
2. Because of 1.) the only correct way to build your Apache with
mod_auth_mysql is to use the following:
$ LDFLAGS="-L/path/to/mysql/libraries" LIBS="-lmysqlclient" \
./configure \
--add-module=/path/to/your/mod_auth_mysql.c
