above v1.4.0 it will not compile in a project with knolleary/PubSubClient on PlatformIO with ESP32Dev

[dominatorstang]

I really like this library and the enhancements made above v1.4.0 sound great, along with the added PlatformIO compatibility being added on v1.5.0. Yesterday I was working on getting back into updating some of my projects and doing all the work in PlatformIO as I move forward. But I could not get my projects to compile when I add this library.

In Troubleshooting, I find that I was still using v1.4.0 with Arduino IDE so I could continue using pubsubclient with this library because I use them together on many of my projects. But I would like to try versions above 1.4.0 on my projects and use PlatformIO if there is a work around or a fix.

[env:esp32dev]
platform = espressif32
;platform = espressif32 @ 6.8.1
board = esp32dev

It gives about 80 errors with most being about things from ArduinoSTL not being declared...

• Library version: [eg: 1.5.0 & 1.6.0]
• Arduino core: [eg: SAMD v1.8.13]
• Enviroment/IDE: PlatformIO
• Dimmer board: RobotDYN
• Board: ESP32Dev

sivar2311 did help me with a workaround on post https://community.platformio.org/t/multiple-arduinostl-errors-when-trying-to-move-project-from-arduino-ide/44472/5.

Move the Dimmable Light library from .pio/build/libdeps/esp32dev into the /lib folder.
Delete the library form the lib_deps in your platformio.ini
Delete the ArduinoSTL library from .pio/build/libdeps/esp32dev
