[Bug 1183262] [NEW] dh_translations looks for po/Makefile in source tree, fails with CMake when built out-of-source

[Olivier Tilloy]

Public bug reported:

If a package doesn’t use intltool to manage its translations, the
build_pot() function of /usr/bin/dh_translations looks for po/Makefile,
and if it exists it executes "make $domain.pot". This works for packages
that ship a Makefile in the po directory, but if the Makefile is
generated at build time (e.g. when using CMake) in a separate build
directory (which is usually the case when building packages), then
dh_translations fails to find po/Makefile, even though it exists in the
build directory.

Here is the relevant code:

    if ($use_intltool) {
        …
    } else {
        return unless -e 'po/Makefile';
    if ($domain) {
        # let the Makefile itself handle it
        @cmd=('make', $domain . '.pot');
    }

@cmd should be passed an additional '-C', $builddir.
