It seems that the downloading of the archive stored on sourceforge
fails sometime.
Use the archive stored in our server (download.kiwix.org) instead.
And also move to the last version of lzma.
- Dependency are installed "striped".
- Our project are build "debugoptimized" by default and "release" when
building release instead of "debug"
We need to update the `base_deps_meta_version` as we are changing how
dependencies are compiled.
We new release of a project is made, projects dependending of it are
rebuild and republish to keep the binaries up-to-date.
To avoid overwrite the already build archives and silent the fact that
new archives are available, we need to have a extra build version.
`release_versions[project]` has to be set each time a dependency of
`project` is bump but the project version has not changed.
If the `project` version changes, the `release_versions[project]`
has to be cleared.
If we don't want to release this version again, remove project from
`release_versions`.
See kiwix/kiwix-tools#222
SVN checkout can be pretty long to do (especially if icu serveur is pretty
slow).
By downloading an archive on our own server, we avoid a spending too many
time downloading.
The archive is a simple targz of the SVN checkout.
We build with gcc-5 because of zimSplit using ofstream.swap method.
Latest version of zimSplit doesn't use it anymore so let's compile
everything with default gcc.
See openzim/zim-tools@a959609839
We also explicitly set the list of package to install per job, so
less packages are installed.
