Undeclared NOT_AN_INTERRUPT for Nordic NRF52 plateform

[PJCzx]

Hello @sumotoy

Thx for your work :)

I submitted a fix for relative path of Wire.h and SPI.h headers. This enables me to build correctly on atmelavr plateform but still have an issue on nordicnrf52.

Environment    Status    Duration
-------------  --------  ------------
nanoatmega328  SUCCESS   00:00:03.300
nordicnrf52    FAILED    00:00:02.831

Here are my project confs :

[env:nanoatmega328]
platform = atmelavr
board = nanoatmega328
framework = arduino
lib_deps =
    Wire
    SPI
    gpio_expander

[env:nordicnrf52]
lib_deps =
    Wire
    SPI
    gpio_expander
framework = arduino
platform = nordicnrf52
board = nrf52_dk
debug_tool = jlink

And here is the error part of my console output 👍

Do you have any clue ?

Thx a lot :)
