-Subject: [PATCH 1/3] Make libide's install_dir an absolute path.
-
-As far as I know, this change should be a no-op on all systems where
-Builder works today. However, it is necessary for getting the correct
-shared-library path into generated .gir and typelib files when building
-on Nix, so I'm hoping this is an acceptable change for upstream.

-Subject: [PATCH 2/3] Allow packagers to specify the Python libprefix.
-
-When packaging for Nix, the directory that pygobject finds its overrides
-in is not writable. It'll usually look something like this, and can only
-contain files built by the pygobject package itself:
-
-/nix/store/58qam3zgdcvvsz4g081pp98kg9i5v7rb-python3.6-pygobject-3.26.1/lib/python3.6/site-packages/gi/overrides
-
-This makes Builder's pygobject_override_dir heuristic fail, because
-Builder's libdir is not a prefix of pygobject's libdir.
-
-Fortunately, what Builder actually needs is for its overrides to be on
-the Python import path when it runs, and that's easier to arrange. We
-just need to be sure that Ide.py gets installed to
-
-<libdir>/python<version>/site-packages/gi/overrides
-
-So this patch allows packagers to optionally specify the
-"python<version>" portion of the path, and just constructs the rest of
-the path using Builder's libdir.
-
-The existing auto-detection code is still used unless the
--Dpython_libprefix option is explicitly specified to override it.
