Error when compiling for rpi

I have followed the cross compiling tutorial for qt6 on the qt website here.

When compiling I get this error

What I find strange is that I was able to cross compile a different project no problem with the exact same kit and CMakeLists.txt file.

Here is the CMakeLists.txt for reference

cmake_minimum_required(VERSION 3.5)

project(PROJECT_NAME LANGUAGES CXX)

set(CMAKE_INCLUDE_CURRENT_DIR ON)

set(CMAKE_AUTOUIC ON)
set(CMAKE_AUTOMOC ON)
set(CMAKE_AUTORCC ON)

set(CMAKE_CXX_STANDARD 17)
set(CMAKE_CXX_STANDARD_REQUIRED ON)

find_package(Qt6 COMPONENTS Core Quick SerialPort VirtualKeyboard QuickControls2 REQUIRED)
qt_standard_project_setup()

set(CMAKE_C_FLAGS "${CMAKE_CXX_FLAGS} -fPIC -Wl,-rpath-link, ${CMAKE_SYSROOT}/usr/lib/${CMAKE_LIBRARY_ARCHITECTURE} -L${CMAKE_SYSROOT}/usr/lib/${CMAKE_LIBRARY_ARCHITECTURE}")
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -fPIC -Wl,-rpath-link,${CMAKE_SYSROOT}/usr/lib/${CMAKE_LIBRARY_ARCHITECTURE} -L${CMAKE_SYSROOT}/usr/lib/${CMAKE_LIBRARY_ARCHITECTURE}")

set(SOURCES main.cpp)

qt_add_resources(SOURCES qml.qrc)

add_executable(PROJET_NAME main.cpp backend.cpp  ${SOURCES})

target_link_libraries(rfid_cloner-gui -lm -ldl Qt6::Core Qt6::Quick Qt6::SerialPort Qt6::VirtualKeyboard Qt6::QuickControls2)

I read that it is because the libraries are built with a different compiler than I am using for my project but I don't see how this could be the case if it works for my other project and the CMakeLists.txt are identical (besides project name). Any help is greatly appreciated.
