zmq 小白简易安装C++版

主要参考博客: 在cmake工程中使用ZeroMQ,并加以补充次要博客:Linux下ZeroMQ的编译安装与运行文中提到arm,我只装在linux系统上，原本想用在通信中，最后还是用tcp实现了

#安装libzmq

git clone https://github.com/zeromq/libzmq.git
1. 在当前文件夹内下载libzmq文件夹,建议先cd到你想要放的文件夹
cd libzmq
./autogen.sh
./configure

#安装zmqpp

git clone https://github.com/zeromq/zmqpp.git
1. 同理,找个文件夹放
make -j4 && sudo make install

上述安装完成后查看头文件和库文件路径

如果当前在用户路径下 cd ../../user

头文件路径： /usr/local/include
库文件路径 : /usr/local/lib
