Can't build docker image

[angelgaspar]

Hi, Thanks for your great work.
I'm trying to build the docker image but I'm getting the following error:

76.63 /bin/sh: 1: cd: can't cd to 3rdparty/gst-python/
------

 2 warnings found (use docker --debug to expand):
 - LegacyKeyValueFormat: "ENV key=value" should be used instead of legacy "ENV key value" format (line 4)
 - JSONArgsRecommended: JSON arguments recommended for CMD to prevent unintended behavior related to OS signals (line 40)
Dockerfile:16
