how to find current `PKG_CONFIG_PATH` by `pkg-config --variable pc_path pkg-config` and
`export PKG_CONFIG_PATH=/usr/lib64/pkgconfig:/usr/share/pkgconfig:/usr/local/lib64/pkgconfig/:/usr/local/lib/pkgconfig/`

>* `m4` check not exist then `sudo yum install m4`
>* `g++` check not exist then `sudo yum install gcc-c++`
>* `cmake` check not exist then `sudo yum install cmake`
>* `libxml2` install by yum, `sudo yum install libxml2`
>* `libtool` install by grade, reference: `https://www.quyu.net/info/856.html`, wget download and make
>* `glib` install by yum, `sudo yum install glib2-devel.x86_64`
>* `gtest` install by source, `sh $ git clone https://github.com/google/googletest.git $ cd googletest/ $ mkdir build $ cd build $ cmake .. $ make $ sudo make install`
>* `cjson` install by source, `https://github.com/arnoldlu/cJSON.git` same as `gtest`
>* `glog` install by yum, `sudo yum install glog-devel`
>* `gflags` install by yum, `sudo yum install gflags-devel`
