Locations PCLConfig.cmake and pcl-config.cmake files for PCL library - cmake

Question

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

Answer 1

you should specify the PCL dir for the CMake to find it.
In a terminal run :
$ locate PCLConfig.cmake
Then, add the found folder (without the filename) to your CMakeLists like the following :
set(PCL_DIR "/found/folder/")
#change X.x to whatever version yo installed
Sidenote : /usr/share/pcl-x.x is the usual path to your pcl folder.

I had the same problem when I followed the steps mentioned on the website http://www.pointclouds.org/downloads/linux.html, for Ubuntu 18.
You simply need to run
sudo apt install libpcl-dev
as bionic is not mentioned in the distributions (http://ppa.launchpad.net/v-launchpad-jochen-sprickerhof-de/pcl/ubuntu/dists/)
