Hello and thank you for your answer,
I tried with python 3.10 and added some python line to the “Createtarget.py” to plot the sys.paths .
For the first build, the missing module error was solved. I had an other error of missing file, but i could see the environnement was included in the sys.path.
Then, all next build gave me the missing module error and the environnement was not in sys.path anymore. VScode could reconize the the environnement and thus module, but the building tools seems to be unable to do so.
So, something in cmake seems to be changing the interpreter without notifing me. To be honest, I gave up for now. I’m not comfortable enough with Cmake to debug this.
