Subject: Fix: python bindings OOT build
X-Git-Tag: v2.0.0-pre4~95
X-Git-Url: http://git.efficios.com/?p=babeltrace.git;a=commitdiff_plain;h=5f114259535f7d228f9bb1ae292e00178599a8c0

Fix: python bindings OOT build

All the source files required to build the python bindings with
distutils must be in the same directory, since some of them are
generated by the build system, copy the static ones to the build
directory when it is different from the source directory.
