pcl 1.72 installation question

edit

My source directory contains my testPCD.cpp program and PCL directory with pcl 1.7.2 called pcl-pcl-1.7.2. This was unziped here from tar file from pclcloud home page for 1.7.2 source. I will download and compile ros dependent source as needed but first I need to get catkin_make to find 1.7.2.

This is the error I get from running catkin_make

  Could not find a configuration file for package "PCL" that is compatible
  with requested version "1.7.2".

  The following configuration files were considered but not accepted:

    /usr/share/pcl-1.7/PCLConfig.cmake, version: 1.7.1

CMakeList file from my testPCD project dir is as follows ,removed some things so as not too bulky for listing here

cmake_minimum_required(VERSION 2.8.3)
project(testPCD)


find_package(catkin REQUIRED COMPONENTS
  roscpp
  pcl_ros
  )


## System dependencies are found with CMake's conventions
find_package(Boost REQUIRED COMPONENTS system)
find_package(PCL 1.7.2 REQUIRED)

catkin_package(
  DEPENDS boost
  LIBRARIES
  CATKIN_DEPENDS
  pcl_ros
  )
