Hi, Sebastián!
Libraries from lib folder have a higher priority than ones located in a framework.
I’ve just copied ESP8266WebServer to local lib folder in the project and everything works as expected - PlatformIO uses ESP8266WebServer from lib folder. Am I missing something from your issue? Have you tried to delete entire .pioenvs folder?

You are right! I was having an issue changing the folder name.
