[venv/python dependencies] issues building jiminy with a virtual environment about jiminy

[o-Oscar]

Ok, I found two things that had to be done in order to get my venv to work.

First I had to change the ./build_tools/easy_install_deps_ubuntu.sh file to account for my setup :
I have to add the following line to activate the environment within the bash file : source venv/bin/activate
And change every sudo -u $(id -nu "$SUDO_UID") python3 -m pip... to sudo -u $(id -nu "$SUDO_UID") env "PATH=$PATH" python3 -m pip... in order to keep the right PATH for the sudo user.

Finally, I had to export a new field in PYTHONPATH. Namely : export PYTHONPATH=/opt/openrobots/lib/python3.8/site-packages:$PYTHONPATH

With those changes, I can effectively use jiminy_py from the python of my venv !!!

Actually the easy-install is not very well suited for virtual env, since it is used to install system-wide dependencies, which are supposed to work with the native environment of the system. In this particular setupi would rather recommend to build dependencies from source to avoid any mistake, unless we can really find a way to support both native and virtual env in easy-install script out-of-the-box.

activate the environment within the bash file

Is this really necessary ? Outside is not enough ?
