Thank you very much for your answer Krishna !!!
About the: define a lib_extra_dirs path…Where am i supposed to define it. I read the docs again and they give this example:
lib_extra_dirs = /common/libraries
I mean if i’m supposed to be add this to the platformio.ini file, the problem is that, as each project has its own platformio.ini file, it means i will have to add this line every time i create a new project, and my “goal” would be to simply be able to add libraries from a “global” folder by simply including them with an #include, like you can do in the Arduino IDE, but may be it is not possible (?)
