Hi Lucas,

Yes, this was actually a bug of our build system. Thanks for reporting. 
I have fixed it in the trunk revno 339 introducing the variable 
`ocaml_libraryprefix' (the location of libraries *used* by the project). 
The value of this variable may be different from `libraryprefix', that 
represents the location where we want to install the libraries *built* 
by the project.

Sorry for the delay of our reaction: we were very busy these two last 
week by the evaluation of our laboratory (by the AERES, you are a MCF 
and you can easily imagine the stress ;-)).

Here an example of a CONFIGME suitable, I think, for debian packaging :

% cat CONFIGME
ocaml_libraryprefix=$(ocamlc -where || exit -1)
ocaml_sources=${ocaml_libraryprefix}/caml
prefix=${DESTDIR:-debian/tmp}
libraryprefix=${prefix}/${ocaml_libraryprefix}
configurationprefix=$prefix/etc
documentationprefix=$prefix/share/doc
localeprefix=$prefix/share/locale

Thanks,
Jean-Vincent

Title:
  build system should support setting a prefix

  New

Bug description:
  Hi,

  The way Debian packages builds work is that "make install" is run with
  a custom prefix or DESTDIR variable, so that files are installed in
  the debian/tmp subdirectory. That is usually implemented by specifying
  a prefix during the configure phase, or by setting a variable.

  The custom build system in ocamlbricks does not allow to do that. If
  you override libraryprefix in CONFIGME and set it to
  debian/tmp/usr/lib/ocaml, 'make' then fails to find lablgtk2, because
  it looks for it in debian/tmp/usr/lib/ocaml/lablgtk2/

  It would be better to move away from the custom build system, and use
  something more standard. Since I'm not usually involved in ocaml
  packaging, I cannot make a recommandation, but if needed, I could ask
  the right people.

  Alternatively, this could be worked-around using dirty hacks in the package building process, but:
  (1) these will be very dirty hacks
  (2) it would only fix the problem for Debian
  Generally, it is much easier to improve the build system, since it benefits everybody.

  Thanks,
