PlatformIO fails to build for RP2040 using earlephilhower core (With workaround)

[mlaga97]

Describe the bug

Building with the following platformio.ini:

[env:rp2040]
platform = https://github.com/maxgerhardt/platform-raspberrypi.git
board = pico
framework = arduino
board_build.core = earlephilhower
lib_deps =
  fabianoriccardi/Dimmable Light for Arduino@^1.6.0

fails due to conflicts with the built-in STL, which the dimmable-light documentation recommends solving by adding

lib_compat_mode = strict

to the platform.ini file.

However...

This still fails to build with the following error:

src/main.cpp:4:10: fatal error: dimmable_light.h: No such file or directory

Running pio build with the -v flag shows the following additional information:

LDF: Library Dependency Finder -> https://bit.ly/configure-pio-ldf
LDF Modes: Finder ~ chain, Compatibility ~ strict
Platform incompatible library /Parlor/Lauren/Projects/LARPANet-boards/Firmware/LampDimmer/.pio/libdeps/rp2040/ArduinoSTL
Platform incompatible library /Parlor/Lauren/Projects/LARPANet-boards/Firmware/LampDimmer/.pio/libdeps/rp2040/Dimmable Light for Arduino

For some reason, this library is not counted as being compatible with this platformio configuration.

Workaround

Through some trial and error, I was able to determine that lib_compat_mode = strict needs to be removed and lib_ldf_mode = off added, giving the following working platformio.ini:

[env:rp2040]
platform = https://github.com/maxgerhardt/platform-raspberrypi.git
board = pico
framework = arduino
board_build.core = earlephilhower
lib_deps =
  fabianoriccardi/Dimmable Light for Arduino@^1.6.0
lib_ldf_mode = off

In theory lib_ldf_mode = chain+ or lib_ldf_mode = deep+ should work since the #include <ArduinoSTL.h> is properly #ifdef'd, but it doesn't for some reason.
