下载

fmt的下载地址为https://github.com/fmtlib/fmt/tags，以下载版本8.1.1为例，下载后文件为fmt-8.1.1.tar.gz。

编译

使用命令tar -zxvf fmt-8.1.1.tar.gz进行解压，解压完成后文件夹fmt-8.1.1中目录结构如下：

.
├── ChangeLog.rst
├── CMakeLists.txt
├── CONTRIBUTING.md
├── doc
├── include
├── LICENSE.rst
├── README.rst
├── src
├── support
└── test

使用命令mkdir build创建构建目录，然后进入build中(cd build)，使用命令cmake ..构建工程，

[root@instance-1apocjsh build]# cmake ..

再使用命令make -j16进行编译，

最后使用命令make install DESTDIR=目标目录进行安装。

[root@instance-1apocjsh build]# make install DESTDIR=xxx

安装完成后，将目标目录中的include目录和lib64目录放入到新建的fmt目录，最终供外部使用的fmt目录结构如下:
