VSCode + PIO IDE + mbed: How to include the source files existing in framework-mbed while building

I wanna add a I2CEEBlockDevice class (while is in the components dir) instance in my mian.cpp, but it caused a not including error, which is showed as follows:
So how would i fix the problem? Modifying some kinds of configuration files? Add new files or …?
And if i wanna add the file system source files,which are same in the components dir, CAN I ALSO do the same way?

Usually you’d use the mbed_app.json configuration file to add the storage feature and subcomponents like shown in, but that was reported to have an error too. Either try that again or workaround it as the issue says.

Does it compile in mbed-studio or mbed-cli?
