+Subject: [PATCH 3/9] fix(setup.py): compute install directory before outside
+ build_extension
+
+This fixes builds with `setup.py develop`/`pip install -e`.
+
+build_ext.run() unsets build_ext.inplace before running
+build_extension(), and only restores it before calling
+copy_extensions_to_source(). Because the cmake extension has to know the
+real install directory in build_extension(), we need to compute it
+before calling build_ext.run() and then retrieve it in build_extension().
