 #### Install build dependencies for taos-tools 
 To build the [taos-tools](https://github.com/taosdata/taos-tools) on CentOS, the following packages need to be installed.
 ```bash
-sudo yum install xz-devel snappy-devel jansson-devel pkgconfig libatomic
+sudo yum install libz-devel xz-devel snappy-devel jansson-devel pkgconfig libatomic
 ```
+Note: Since snappy lacks pkg-config support (refer to [link](https://github.com/google/snappy/pull/86)), it lead a cmake prompt libsnappy not found. But snappy will works well.
