boost process 设置子进程工作目录
通过boost::process::start_dir 指定
std::string cmd = (AppContext::GetBinDir() / "agvtask.exe").string(); auto pipe_stream = std::make_unique<boost::process::ipstream>(); auto car_process = std::make_unique<boost::process::child>(cmd, boost::process::start_dir(AppContext::GetBinDir().parent_path() / "bin")); //, boost::process::std_out > *pipe_stream
