Some context since I am a newbie here:

I've followed the official guide to build a boot2qt image for raspberry pi 4, build the SDK to it and include it in QT Creator.
The chosen machine value was "raspberrypi4-64".
I am using as a development host (machine running QT Creator) a Macbook Pro with Ubuntu 20.04.

Now, I am trying to use pigpio library to handle gpios.

I've followed this steps:

wget https://github.com/joan2937/pigpio/archive/master.zip
unzip master.zip
cd pigpio-master
make

Then I moved the compiled folder to the root of my app, and imported the library using the UI.
This was added to my .pro:

win32:CONFIG(release, debug|release): LIBS += -L$$PWD/Libraries/pigpio/release/ -lpigpio
else:win32:CONFIG(debug, debug|release): LIBS += -L$$PWD/Libraries/pigpio/debug/ -lpigpio
else:unix: LIBS += -L$$PWD/Libraries/pigpio/ -lpigpio

INCLUDEPATH += $$PWD/Libraries/pigpio
DEPENDPATH += $$PWD/Libraries/pigpio

win32:CONFIG(release, debug|release): LIBS += -L$$PWD/Libraries/pigpio/release/ -lpigpiod_if
else:win32:CONFIG(debug, debug|release): LIBS += -L$$PWD/Libraries/pigpio/debug/ -lpigpiod_if
else:unix: LIBS += -L$$PWD/Libraries/pigpio/ -lpigpiod_if

INCLUDEPATH += $$PWD/Libraries/pigpio
DEPENDPATH += $$PWD/Libraries/pigpio

win32:CONFIG(release, debug|release): LIBS += -L$$PWD/Libraries/pigpio/release/ -lpigpiod_if2
else:win32:CONFIG(debug, debug|release): LIBS += -L$$PWD/Libraries/pigpio/debug/ -lpigpiod_if2
else:unix: LIBS += -L$$PWD/Libraries/pigpio/ -lpigpiod_if2

INCLUDEPATH += $$PWD/Libraries/pigpio
DEPENDPATH += $$PWD/Libraries/pigpio

When i try to build the project those errors are not allowing me to proceed:

Can anyone help me to figure this out?
I've never worked with boot2qt, so it has been a painful first experience.
:D
