undefined symbol when importing libraries built with pip install

Currently on the main branches of each project. This behavior occurs also on backend_cuda.

commits :

• core : 928cb23
• backend_cpu : a7666da
• learning : 74739318

repoduce the bug by simply trying to build & import aidge_learning :

1. setup env

git clone git@gitlab.eclipse.org:eclipse/aidge/aidge.git
cd aidge
git submodule update -i
cd aidge/
pip install aidge_core -v
pip install aidge_backend_cpu -v
pip install aidge_learning -v

2. create bug :

python -c "import aidge_learning"

3. result

Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/home/greg/miniconda3/envs/test_release/lib/python3.8/site-packages/aidge_learning/__init__.py", line 11, in <module>
    from aidge_learning.aidge_learning import *

 undefined symbol: _ZN5Aidge19SequentialScheduler7forwardEbRKSt6vectorISt10shared_ptrINS_6TensorEESaIS4_EE

NOTE Trying to import aidge_core and/or aidge_backend_cpu before that doesn't solve the problem.

added StatusTODO label

added Bug 🐛 Compilation labels

when reproducing the issue I get a different error :

This issue arises for every repository that holds more that 1 dependency.

@gregkub I have trouble reproducing the issue. The steps you provided do not throw any error for me with the main branch

I used the same commit version as @gregkub and cannot reproducer the error either, will try on a different server.

I am in shame : the error came from me, I had an artifact of install in /usr/local/lib that spoiled the installation.

This is a good argument for the docker release.
