Subject: [PATCH v6 1/4] pylibfdt: allow build out of tree
Date: Wed,  4 Nov 2020 23:45:24 +0400	[thread overview]
Message-ID: <20201104194527.986901-2-marcandre.lureau@redhat.com> (raw)
In-Reply-To: <20201104194527.986901-1-marcandre.lureau-H+wXaHxf7aLQT0dZR+AlfA@public.gmane.org>

From: Marc-André Lureau <marcandre.lureau-H+wXaHxf7aLQT0dZR+AlfA@public.gmane.org>

With meson, we have to support out-of-tree build.

Introduce a --top-builddir option, which will default to the current
directory to lookup generated filed such as version_gen.h and output
directories.

Other source paths are derived from the location of the setup.py script
in the source tree.

--build-lib is changed to be relative to the current directory, instead
of relative to setup.py. This has less surprising results!
