用如下命令编译UTbot的example 程序，

/mnt/data/maml2/utbot/2023.12.0/utbot_distr/install/bin/cmake -DCMAKE_ASM_USE_RESPONSE_FILE_FOR_INCLUDES=OFF -DCMAKE_C_USE_RESPONSE_FILE_FOR_INCLUDES=OFF -DCMAKE_CXX_USE_RESPONSE_FILE_FOR_INCLUDES=OFF -DCMAKE_ASM_USE_RESPONSE_FILE_FOR_OBJECTS=OFF -DCMAKE_C_USE_RESPONSE_FILE_FOR_OBJECTS=OFF -DCMAKE_CXX_USE_RESPONSE_FILE_FOR_OBJECTS=OFF -DCMAKE_ASM_USE_RESPONSE_FILE_FOR_LIBRARIES=OFF -DCMAKE_C_USE_RESPONSE_FILE_FOR_LIBRARIES=OFF -DCMAKE_CXX_USE_RESPONSE_FILE_FOR_LIBRARIES=OFF -DCMAKE_EXPORT_COMPILE_COMMANDS=ON -DCMAKE_EXPORT_LINK_COMMANDS=ON ..

报如下错误

在main.cpp 同级目录， 

vi 编辑CMakeLists.txt

在set(CMAKE_C_STANDARD_REQUIRED ON) 语句后

添加一个set语句 set(CMAKE_CXX_FLAGS "--stdlib=libc++")

保存退出，重新用上述的语句来编译，就成功通过，不报这个error了
