Please make sure to read Library Dependency Finder (LDF) guide first.
DirPath | Multiple:
A list with extra directories/storages where Library Dependency Finder (LDF) will look for dependencies.
This option can also be set by global environment variable
This is a not direct path to a library with source code. It should be a path
to storage that contains libraries grouped by folders. For example,
D:\PlatformIO\extra\libraries but not
[env:myenv] lib_extra_dirs = /common/libraries /iot/libraries
