Centos7 安装部署pgAgent提示报错

Centos7 安装部署pgAgent 提示报错,实际已经安装好了PostgreSQL,请问是什么原因,要怎么解决呢？
[root@master pgAgent-4.0.0-Source]# source /home/postgres/.bashrc
[root@master pgAgent-4.0.0-Source]# cmake ./
CMake Error at cmake/FindPG.cmake:131 (MESSAGE):

Call Stack (most recent call first):

-- Configuring incomplete, errors occurred!

你要cmake 是？ 继续编译安装？
