the -fmacro-prefix-map compile option is gcc/clang/armclang specific compile option, and greenhills do not recognize this compile option, if we add this option is CMakeLists.txt, the following warning will be reported when each file is being compiled: ccarm: Warning: Unknown option "-fmacro-prefix-map=/home/guoshichao/work_profile/vela_os/vela_car_5/nuttx=" passed to linker ccarm: Warning: Unknown option "-fmacro-prefix-map=/home/guoshichao/work_profile/vela_os/vela_car_5/apps=" passed to linker ccarm: Warning: Unknown option "-fmacro-prefix-map=/home/guoshichao/work_profile/vela_os/vela_car_5/vendor/flagchip/boards/mann/dcu/fc4150f1m-labm_a1=" passed to linker ccarm: Warning: Unknown option "-fmacro-prefix-map=/home/guoshichao/work_profile/vela_os/vela_car_5/vendor/flagchip/chips/fc4150=" passed to linker ccarm: Warning: Unknown option "-fmacro-prefix-map=/home/guoshichao/work_profile/vela_os/vela_car_5/nuttx=" passed to linker ccarm: Warning: Unknown option "-fmacro-prefix-map=/home/guoshichao/work_profile/vela_os/vela_car_5/apps=" passed to linker ccarm: Warning: Unknown option "-fmacro-prefix-map=/home/guoshichao/work_profile/vela_os/vela_car_5/vendor/flagchip/boards/mann/dcu/fc4150f1m-labm_a1=" passed to linker ccarm: Warning: Unknown option "-fmacro-prefix-map=/home/guoshichao/work_profile/vela_os/vela_car_5/vendor/flagchip/chips/fc4150=" passed to linker Signed-off-by: guoshichao <guoshichao@xiaomi.com>
