问题描述及复现步骤:

命令行直接编译是可以通过的，但是通过CmakeList 编译是 通不过

cmake_minimum_required(VERSION 3.5.1)

project(learn_test)

#告诉CMAKE是进行交叉编译

set(CMAKE_CROSSCOMPILING TRUE)

#设置此时进行编译的系统

set(CMAKE_SYSTEM_NAME "Linux")

#指定交叉编译器的路径

set(COMPILER_PATH "/opt/sysroot/firefly-arm64-sysroot-18.04/usr")
set(CMAKE_CXX_COMPILER "${COMPILER_PATH}/bin/aarch64-linux-gnu-g++")

add_executable(learn_test src/test.cpp)
