[Pkg-openldap-devel] where are the configuration options used by Debian to build a package

[Benin Technologies]

Hi,

I'd like to install from source the latest release of openldap (2.4.33) 
on Debian, but I'd like to do it using the same configuration options as 
Debian when installing through the packages (i.e. the same directories, 
and so on...)

Where can I find the configuration options used by Debian for their 
package ?

PS : on various websites they talk about a debian/rules file which is 
supposed to contain these informations, so I download Debian's OpenLDAP 
source for their package (2.4.31) on 
http://packages.debian.org/source/sid/openldap, but I didn't find any 
"rules" file in it.

Thanks.
BT
