vi CMakeLists.txt
# 添加以下内容
set(CMAKE_SYSTEM_NAME Linux)
set(CMAKE_SYSTEM_PROCESSOR aarch64)
set(tools /root/t507/sdk_v2/V2.0/out/gcc-linaro-7.4.1-2019.02-x86_64_aarch64-linux-gnu)
set(CMAKE_C_COMPILER ${tools}/bin/aarch64-linux-gnu-gcc)
set(CMAKE_CXX_COMPILER ${tools}/bin/aarch64-linux-gnu-g++)
set(ROOT_DIR /root/test-2023-05-08/terminal_bak/lib_new)


mkdir build
cd build
