Instead of having the run_command function setting the
env from the buildEnv, this is the dependency that create the
env and then pass it to the run_command function.
This way, each dependency will be able to set a specific env.
We need to be able to build libzim as shared lib while using all
other dependencies statically (to not have libxapian.so, ... to distribute)
This add a new platform (static=False) that make all dependencies being
build in a static platform.
This is the big change !!!!
Instead of handling target as primary object and prepare/build targets,
we are handling build steps.
A build step may be a source (preparation) or a build (of the source).
Actualy, a step is a tuple (context, Builder or Source).
The context define the context of the step. It can be :
- 'source', for a Source step
- 'neutral' or the name of a platform for Build step.
Target becomes a "Class only" class.
Sometime the root_path is dependent of the target platform and sometime
not. But sometime dependent of the build arch :/
[TODO] We should move the cross_file generation to the PlatformInfo class.
