Library Frustration

PlatformIO wants to have all the libraries, right? Sounds like it.
Why wouldn’t you have a utility for people to submit libraries for inclusion?
I saw the command prompt text, but it didn’t work. Couldn’t find the file specified, so I guess I don’t have the right application.

These are the errors:

This is the library, in the lib folder:

This is the .ini file, and the library is also in my libraries directory.

platform = espressif32
board = esp32doit-devkit-v1
framework = arduino
lib_extra_dirs = ${sysenv.HOMEDRIVE}${sysenv.HOMEPATH}\Documents\libraries

How can I make this chronic problem of adding libraries go away? Does having the library in the /lib folder do anything to the same library in the /libraries folder? I’m failing to do something.

Here’s the code:

CurieBLE is a BLE library for Intel Curie Boards (ArduinoCore-arc32/libraries/CurieBLE at master · arduino/ArduinoCore-arc32 · GitHub, GitHub - arduino/ArduinoCore-arc32). You’re compiling for an ESP32. I don’t think this library should work for an ESP32. Does it compile in the Arduino IDE? With which settings?

… that makes sense. I wonder why it was chosen and written into this elaborate program advertised for ESP32. I mean,. written by Intel.

Thank you. I’ll keep looking for something with a generic library.

Arduino is using CurieBLE in their examples:

The important thing is this: I OWN THIS LIBRARY. Why isn’t PlatformIO facing that fact?
