Hello

Thanks for writing this makefile. I did some changes to it so I can use it on multiple projects.
I was careful to not remove any functionality that already had. So it can still be used as it was designed initially, using the environment variables

Many thanks!
Here follows the changes.

Changes

Added a new json configuration file

Among the .ino file, there's an compilerconfig.json file that has the parameters for the Makefile. Here's an example (I added one of these to your projects):

{
  "config": {
    "fqbn": "esp8266:esp8266:d1_mini",
    "serial": "/dev/ttyUSB0",
    "iot_name": "esp8266-blink",
    "ota_port": "8266",
    "verbosity": "0",
    "ota_pass": ""
  },
  "libs": [
    "Adafruit GFX Library",
    "Adafruit SSD1306"
  ]
}

Added dependencies

I added an extra field for dependencies on the Makefile for the libs, so it can support this extra way manage lib dependencies, and not have to maintain 2 extra files.

Added help

I added an help message so I could test the output, and because it can be useful

Added a new dependency

This to run, requires jq installed on your workstation to handle the json file.

Usage

The usage would then be

make -f ../Makefile help
make -f ../Makefile compile
make -f ../Makefile upload
