title: Locations PCLConfig.cmake and pcl-config.cmake files for PCL library
body: <p>I installed PCL using the following commands.</p>
  
  <pre><code>sudo add-apt-repository ppa:v-launchpad-jochen-sprickerhof-de/pcl
  sudo apt-get update
  sudo apt-get install libpcl-all
  </code></pre>
  
  <p>When I compiled my PCL program with the following lines in <code>CMakeLists.txt</code></p>
  
  <pre><code>find_package(PCL 1.3 REQUIRED COMPONENTS)
  include_directories(${PCL_INCLUDE_DIRS})
  link_directories(${PCL_LIBRARY_DIRS})
  add_definitions(${PCL_DEFINITIONS})
  </code></pre>
  
  <p>I have errors as</p>
  
  <pre><code>CMake Error at CMakeLists.txt:17 (find_package):
     By not providing "FindPCL.cmake" in CMAKE_MODULE_PATH this project has
     asked CMake to find a package configuration file provided by "PCL", but
     CMake did not find one.
  
     Could not find a package configuration file provided by "PCL" (requested
     version 1.3) with any of the following names:
  
       PCLConfig.cmake
       pcl-config.cmake
  
     Add the installation prefix of "PCL" to CMAKE_PREFIX_PATH or set "PCL_DIR"
     to a directory containing one of the above files.  If "PCL" provides a
     separate development package or SDK, be sure it has been installed.
  </code></pre>
  
  <p>I can't locate PCLConfig.cmake and pcl-config.cmake in my system.</p>
  
  <p>I did like</p>
  
  <blockquote>
    <p>locate PCLConfig.cmake</p>
  </blockquote>
  
  <p>/home/ttt/.local/share/Trash/files/PCLConfig.cmake
  /home/ttt/.local/share/Trash/files/DemoApplications-master/Calculus/tv_auto_on_off/voxel-sdk/libvoxelpcl/VoxelPCLConfig.cmake.in
  /home/ttt/.local/share/Trash/files/config/VoxelPCLConfig.cmake.in
  /home/ttt/.local/share/Trash/files/voxelsdk.2/config/VoxelPCLConfig.cmake.in
  /home/ttt/.local/share/Trash/info/PCLConfig.cmake.trashinfo
  /home/ttt/Softwares/voxelsdk/config/VoxelPCLConfig.cmake.in
  /usr/lib/cmake/VoxelPCL/VoxelPCLConfig.cmake</p>
  
  <p>Does it make sense?</p>
  
  <p>I tried like</p>
  
  <pre><code>set(PCL_DIR "/home/ttt/.local/share/Trash/files/PCLConfig.cmake")
  find_package(PCL 1.3 REQUIRED COMPONENTS)
  include_directories(${PCL_INCLUDE_DIRS})
  link_directories(${PCL_LIBRARY_DIRS})
  add_definitions(${PCL_DEFINITIONS})
  </code></pre>
  
  <p>But still have the same error.
  How to locate PCLConfig.cmake in my system?
  Thanks</p>
