I'm trying to cross-compile libjpeg for RPi Pico, I'm using arm-none-eabi-gcc for this purpose. This is the command that I used to compile it:
cmake -DCMAKE_TOOLCHAIN_FILE=C:/pico-sdk/cmake/preload/toolchains/pico_arm_gcc.cmake -DCMAKE_C_COMPILER=arm-none-eabi-gcc -DCMAKE_CXX_COMPILER=arm-none-eabi-g++ ..
But it generated the following output:

I'm rather new to cross-compilation and libjpeg, what am I doing wrong here? My OS is Windows 10.
